I’m here cuz my dad is busy and my brothers are at college... Guess it’s my turn to take care of the lights this year! This video is helpful for a newb like me. Wish me luck!
I just bought this tool (2022). I had been struggling for YEARS with mini Xmas lights. NO MORE! I actually gave a cheer when I pulled the trigger and my set came back to life. Truly a necessity.
When I saw the video was 40 minutes I was like 😅 that’s way too long, what am I getting myself into?! But this video is so helpful, thorough and concise! Thank you for sharing so much helpful info in a well made professional video
THANK YOU!!! I’ve used the Lightkeeper Pro for years with great success. However, this year I had one section of my tree that I could not get to light. After watching this video I was able to determine the problem and I would never have without the help. Thank you so much.
This video is hands down, the absolute best, video I have ever seen made in my life that explains how miniature light strands function and how to fix them with this product. I got turned onto this product at my local American sale store 6 years ago that had a promo video playing at the store display caught my attention. I have fixed at least 3 dozen light sets with this along with 4 pre lit artificial Christmas trees that were going to be discarded In fact, my relatives call me when their lights go out and I'm none too happy to be a "semi" pro miniature light repairman who gets applause when I make stubborn broken light strands relight after repair. I want to also add that lightkeeper pro company also makes replacement miniature bulbs sold in separate packages . They are the brightest, highest quality replacement bulbs I have ever seen with extra long wires that make it easier to rethread miniature light sockets. I only use lightkeeper pro brand bulbs in ALL my brands of miniature christmas light strands that go bad. You need to understand the importance of using the correct voltage replacement miniature bulb in your set as they ALL look identical in size and shape but the filament inside each little bulb is what separates them. You could have either a 2.5 volt 3.5 volt 6.0 volt 7.0 volt 12.0 volt Clear or colored miniature bulb for your set depending on how many lights your set has. If you use the wrong voltage replacement bulb, you will ruin your light set so always keep the box or instructions or write down somewhere what each set correct replacement bulb voltage is like I do.
You also have to pay attention to wattage. I had a set that used 2.5v 0.43w bulbs, instead of the standard 0.425w. If a 0.425w replacement was used, it would burn slightly too hot.
That was extremely helpful. I'm glad I took the time to watch the whole thing. I have two long sets connected together along my wall outside. One is 100 lights and the other is 200. Each had a 50 light section that was out. I couldn't use the shunt method, probably due to too many burned out bulbs. I was able to use the audible interruption finder and after multiple bulb replacements everything is working. I am thrilled. I never understood before that there were multiple serial sets connected end to end. The only comment I have is that I cannot reverse the polarity by turning the male part of the plug 180 degrees because there is a larger and smaller prong that can only fit into the outlet in one direction. Between the device and these instructions I really feel like I can enjoy my lights so much more. Thank you!
This is the best tool for repairing light strands where complete sections are out. I had a socket on a new light set that was bad and without this tool I would have thrown the set out. Just buy it you will not be sorry.
Your detailed instruction video is among the best I've ever had the benefit of watching! Brian, Ken, John and your anonymous intro-man do a fantastic job going step-by-step with such polished professionalism. I have several LightKeeperPro tools. I will endeavor to put them to effective testing work using the guidance from your excellent video. Thank you!
I wish I'd watched this a few years ago when our expensive prelit garland failed, or my very expensive tree with light failure back around the time this video was first posted! Dealing with light issues on my current tree - just ordered the right bulbs and a LightKeeper Pro - and now watching this video so I can (hopefully) save my current prelit tree's lights for this Christmas season! Thanks for this detailed video, and wish me luck!
As a physicist (like the real one), this video satisfied my need to understand how it works. I certainly understand the series and parallel circuit but don't understand why one light bulb is dark but others are still on, until I found in this video about stunts in the bulb. I also have puzzled what the trigger actually does . Now, I understand the current generated by the piezo can burn the stunt to conduct the circuit. What a smart design! Once you know the principle, how to fix the problem is just so straightforward. I actually suspected if this tool is effective when I tried it and got confused by reading the instruction, until I come to this video. Although I could just buy a new set of lights, it turned out it just gave me so much fun by solving this problem and understand how this work. This 20 bucks tool PLUS this extremely clear explanation gave more fun than any video game I played.
I've had this tool for years...in the Xmas box...never used it. My wife bought it and I've never needed it...until now!! No instructions..yikes...this video is Awesome!!!! Thank you so much..very articulate and focused...well done. 👍
Came home to a light strand out in the center of our tree. LightKepper Pro made for a quick repair identifying a faulty socket. Thank you very much! Merry Christmas
Great Video kudos, had a light set that was driving me crazy! Half way through It I had the answers and had it fixed in no time, I saw the commercial and ran right to Meijers and got one last night great buy money well spent!
I am sure glad I found this video. It was absolutely perfectly explained. I had watched to videos before this one and they were OK , they explained and showed how to use the tool, and that is exactly why I am here I was curious enough to want to know if there was a tool like this so I went on TH-cam. We had 4 strands of lights, one worked the other three didn't and it got me wondering if there were fuses involved because the three strands that none of the bulbs lit up but I couldn't tell where a fuse would be until I watched your video and sure enough I check all the plugs and all three had two blown 3 amp fuses in them and that was we because we had had a power surge and outage the very night that all 4 strands had been lit up. So thank u for that informative video and if anybody else is reading this if none of the bulbs are lit on your strand check to see if there are fuses below the little slide out door it is pretty easy to do, thanks again, also I do have a voltage tester that detects power and it lights up and beeps but I am definitely going to get me your tool as soon as I can.
At least your lights didn’t die AFTER the tree was lit, and decorated like mine last night. Half my tree is lit, and now I have to take it apart to fix it!!! Yay me
Awesome tool. I have a prelit tree and some 30 to 50 lights went out. I thought I'll spent 10 minutes taking the string of the tree to make it easier one to fix. After trying to shunt the first bulb I noticed one flickering along the string of dead bulbs. Once that was replace 80% of the string light came back to light. Replaced 10 more dead ones and voila my tree is lit up again. I recommend taking the part of your prelit tree that's dead. It's so much quicker and easier to lay it out than trying to trace it along the tree.
4:39 In a series circuit 120V travels through the circuit but each bulb on a 50 light strand use 2.5 V . Its the sum of the bulbs voltages totaling 120V. Where in a parallel string each bulb gets 120V because each socket is an independent circuit . In a series set with 100 bulbs its actually a parallel of 2 series circuits of 50 bulbs and so a 100 bulb string still uses 2.5 volts per bulb. Its crucial to promptly replace burned out bulbs even if the string remains lit. In the example of the 50 bulb string if one bulb burns out you now have more voltage going to each bulb and so 1 burning out is not a problem but as more burn out the rest are getting higher and higher voltage and will begin to blow other bulbs rapidly until the set fails because the fuses will blow if the other bulbs take on the additional current left by the failed bulbs
Hi. Thank You for this video. I got a Ligth Keeper Pro, I didn'd undestand their instructions until I saw your video. Thanks. Like up. Regards from Costa Rica 🇨🇷
I've been using one of these for the last three years and it's been phenomenal. So many light strings saved by it. I've even brought pre-lit trees back from the grave. I'll write a more thorough review at some point but thank you for making yet another holiday season bright.
I had forgot to mention that my wife had thrown the three that didn't work into the garbage and I hate that being the type of person I am I like to try and fix things and that got me wondering if there was a tool, and that brought me to TH-cam and eventually your video. I saved it so I can watch and share it.
The entire top section of my tree isn't working but when I use the voltage detector, I hear a continuous beeping in some sections and a slower beeping in others. There isn't any silent section. Do I replace all the slow beeping sections instead?
I found the information on the shunt to be enlightening. I knew about the shunts and understood fundamentally how they work. I always assumed they were some sort of fancy wire. Nope. Just aluminum and utilizing the aluminum oxide layer as the insulation, clever. We had two fancy wall decorations that didn't work. I was going to throw them out. Used the instructions from the video, canniblized one of the two decorations, and got one to work and one for spare bulbs. One's better than none,, so we're good for a few more years. The LightKeeperPro is a good tool, it does have a learning curve this video helps with. However, I don't think it could have helped the light string the squirrels got to the other year.
Great information video but at @20:01 his comment is a bit misleading during the voltage tester instructions. He says you can “identify the wire that has current flowing through it, and one that does not”. This is not technically true because neither wire has current flowing through it. In fact, if current was flowing through any wire, there would be a complete circuit and you would have light. What he should have said is “you can identify what wire has a voltage and what wire does not”. In reality, the voltage is interrupted by an open circuit, therefore on one side of the lamp you have a 120v voltage, and on the other side of the lamp, that wire would have no voltage. In other words, because of the open circuit, no current is flowing through any wires.
Very helpful video. Thanks for putting it together. May I suggest that you add an index in the description to make it easier to reference specific parts of the video in the future please?
Stephen Shanko, Normally I would be saying the same thing, The problem is if you were to make a quality string the bulbs have a limited life, In a short time you are going to have to replace all the lights in that string in order to preserve it, Or chase the last of the aging bulbs as they fail, It only takes a few bulbs out to raise the voltage, this begins a cascade on the older bulbs. But I understand I have led roof lights 5 years old while my reindeer lights corroded in one.
A nce adjustment of my problem. I developed much of the plans but 1) 20 pulses.. I was told 3, I used 5 or 6!! 2) I have a wired angel about 5' x 7' who has the metal conduction of the signal. The mini bulbs are next to each other. Over 30 years, I have had to pull the bulbs and test them as I thought the signal was carried by the steel frame. It has been a challenge as all worked until I hauled the angel to the location. The left lobe of the "skirt" is dead. Concerning the conduction of the signal on the steel wire, it has been a bear. I appreciate your lessons. I found the "Lightkeeper" back then, then about 10 years later I came across the Pro.
Ok I’m trying to fix a prelit tree and here is my problem. First the strand doesn’t jump nicely from one branch to the one next to it, they are all over the place. Then there are some bulbs with an extra side portion (looks like a sidecare) with what I’m guessing is a ground wire. These then have three sets of wires moving off them in different directions. So following the voltage gets a bit tricky. My problem is that as I move along the wire I get a strong beeping but then it falls off and does a double beep. Not silence and not continuous beeping. Does that mean the voyage is low or what? I have replaced many of the bulbs but to no avail. I actually had one set that came on while I went to purchase your product. Why would they do that?
Thank you for the detailed tutorial on troubleshooting and repairing this frustrating holiday issue. Your explanation on how when a light burns out but the shunt works that the electrical load is spread out over the remaining bulbs in the circuit and that it is important to replace it immediately to preserve the remaining bulbs, otherwise they will burn out at an accelera ted rate (The Cascade Effect) As I was beginning the process of finding the problem areas, I quickly realized that entire lengths were actually burned out and 3 @40 bulb sections would need all the bulbs replaced.....grrrr. These lights are on an artificial prewired tree and can't just be laid out on a table top to work on.
Very good explanation. Learned a lot About how the light sets are constructed and the techniques of using the light keeper pro. Thanks so much for taking the time to make this video
I have use this for a few years and i have always had a bulb issue until this time. I was about to pull the section of lights off, but you talked about switch the polarity of the plug.... this helped! Found a socket that part of the wire slid out and wasnt contacting the bulb.... and BAMM! The voltage detector kept making me look here... and well that is how i found it .... thank you :)
I changed all the faulty lights on the area that wasn’t lighting up. When I identified the problem using the lighter they all came on but then within minutes all the bulbs I just changed burned out leaving the old black residual on the original bulbs previously observed. I also identified an area on the wire that was not picking up on the voltage tester. I tried to reset all the lights on those isolated areas but still nothing. Help!
The problem is that 10 years later, after this video was made, they've changed the net lights. Now, there are hooks at the top of the bulb to string them together. There is no way to insert the bulb housing into the trigger pull. It doesn't fit.
This video is terrific. I wish I would have seen it years ago, and my pre-lit tree would have probably lasted much longer. I am working with the voltage detector and only get a few quick chirps, rather than a continuous signal. Do I need new button batteries for the set, or is there a different problem?
Hi Matthew, I would recommend viewing our "Audible Voltage Detector Part 2" video on our LightKeeper Pro site as it might be able to assist further with this feature. You may just want to jump to the other side of the unlit set section as depending on the polarity of the set, you should get constant beeping on one side or the other of the unlit section. If you have any other questions, please don't hesitate to give us a call at 888-858-2548 to speak to one of our technicians as they are available 7 days a week between Thanksgiving and Christmas.
So far I've purchased about 8 led light sets and none have lasted more than 2 years of light use. Oh by the way, my prelit tree from 2001 is still working thanks to the Lightkeeper Pro...although right now I'm watching this video again because one stubborn section is burned out and I have yet to inspect all the new bulbs I replaced in that section to make sure the wires are making good contact with the socket. The voltage detector seems to activate along the entire strand. The other thing I do to keep the new bulbs lasting longer is I made my own dimmer switch attached to an extension cord used solely for the main plug for the tree, and I turn down the voltage going to the entire tree. It's fun because I can choose to illuminate it very dimly like candlelight in a dark room and it's more aesthetically pleasing than blinding full brightness. I can also turn the tree on and off with my foot on the dimmer switch, no need to bendover.
well I've watched a few different videos on fixing the light set. I was able to fix one right away, I've learned a little about electricity...now when I tested the light bulbs they don't lite on the lightkeeper...am I doing something wrong? 'Q...if the socket is damaged cause it doesn't have a replaceable fuse, is that it for the set? The other half I got to work? What do I do?
If only half your strand is working, did u try testing the fuses? One of them may be out. (I was able to fix this same problem that way on one of my sets)
I purchased the tool and used it to fix the Christmas tree - a section of the tree didn't operate. I found the dead light bulb (2.5V incandescent) finally. So, I took out the deal bulb, tested it and made sure it was dead. I replaced it with a new bulb, tested it using the light keeper pro, and plug it back to the socket. After I switched on the tree, the section worked but only for less than one second. Then took out this new light bulb; it is dead. I took out every incandescent bulb and tested them one by one. They all are dead. What could cause the problem? I am going to replace these 50 light bulbs and doubt if they all will be gone within a second.
Hi Frank, I'm not sure I fully understand your question but you can reach out to our technicians at 888-858-2548 to see if they can be of any further assistance. They are available 7 days a week between Thanksgiving and Christmas. Wishing you Happy Holidays!
I want a version of this video where my millennial ass gets frustrated with my Christmas lights and my dead grandpa's ghost yells at me for just saying I'm buying new stuff instead of fixing them and then I'm haunted by the ghosts of string lights, oversize decorations, and pre-lit christmas trees. I wake up and find a lightkeeper pro underneath my half-lit christmas tree and I use it to repair my decorations. Outside, snow is falling.
That's all good and well when you have your lights set on a table but when the damn thing is wrapped and tangled on the those fake trees, boy, you will be cursing everyone for hours. The only way is the untangle the mess and stretch the lights set, to be able to find where the problem is.
The instructions were good up until you fix the brass contact. I did everything to the letter, but the brass contacts would not remain in their channel. This is glossed over like its a piece of cake. In the meantime, I'm still trying to put these in their channel and they do not want to stay put. Now i have to find another video that might address this issue (not likely). Pretty disappointed in the video.
OK, I have a set of blue icicle lights that don't light at all. I tried the quick fix method, No luck. I tried the Audible Voltage detector and it beeped all through the strand. I did try the Quick Fix again and still nothing. I did put new batteries in the unit. ... ANY SUGGESTIONS???
I've been having the same issue on a strand of lights & after carefully rewatching the video, I believe that we may be getting a false reading with the voltage detector due to holding it too close to the wire, hand interference, or not using it to test near the glass of the bulb. Gonna try again & see how that goes...
The bulb puller you demonstrate here does not fit my Balsam Prelit Tree bulbs. The plastic base is too large to fit in the hole of the tool. I have yet to find an easy way to pull out these bulbs.
Just bought this product today. Didn't work for me. The bottom and top of my tree is working but the middle is not is not. The lights were already on the tree when it was bought new. With the top and bottom working and not the middle; this tells me that there is current going through the tree from bottom to the top. I watched this vid and about 5-7 on their website www.lightkeeperpro.com but nothing has worked. Changed all the burnt bulbs. Tried the trigger thing, and also tried the button on the top. Pointed the gun at the 1st bulb got nothing, I changed the polarity and got the beeping sound. Tracing the wire, I would get the rapid beeping sound on one of the lit bulbs then about 4-5 lit bulbs down the line, I would get nothing, even though it was lit. Trying again, I would get the rapid beeping sound on one of the lit bulbs then about 4-5 lit bulbs down the line, again nothing. Same thing would happen at the top of the tree as well, still nothing,,,,
Spend $13 and buy and actual LED strip from ebay or Amazon. Not those janky overpriced same-as-the-old-ones strings with LED bulbs. Get a ribbon strip. Its a solid strip that NEVER goes out like ALL stupid POS string lights do. You get a remote and a variety of color and pattern options. Once you string it inside your tree you don't see the strip but the lighting is amazing. This isn't 1900, its 2020 and you don't ride a horse to work. Your great grandfather's Christmas lights should have been obsolete 50 years ago. Stop the insanity and embrace that which is better in every way. Nobody should have even had to make this video. Your LED strips will last 20 years without a single light going out. Dollar for dollar the value is vastly superior. You don't have to ruin your Christmas before it comes, haggling for hours with crappy string lights. If you do, its your own fault. Skip this video, and jump straight to the video titled "Why do I make life so hard for myself?".
Here's a better video in one second: BUY LED STRIPS. Everything this video discusses and everything it misses are all remedied forever by doing this one thing.

Clear or colored miniature bulb for your set depending on how many lights your set has. If you use the wrong voltage replacement bulb, you will ruin your light set so always keep the box or instructions or write down somewhere what each set correct replacement bulb voltage is like I do.
Hi Bob, sounds to us like you are a true Pro...not a semi-pro! Thank you for the support and kind words! We wish you a Happy New Year!

Yes. Red is incandescent. Yellow is led. I think. Just got it n made hubby make sure he got the right one

Don’t worry. I also bought the tool and obey all the laws of thermodynamics in my house
Most came to see 14:00 through about the 18 minute mark for the shunt fixer part you do with the trigger.
Thank you for this! I'm shocked at how much information there is.
I've had this tool for years...in the Xmas box...never used it. My wife bought it and I've never needed it...until now!! No instructions..yikes...this video is Awesome!!!! Thank you so much..very articulate and focused...well done. 👍
I never thought a video on holiday light repair could be interesting, but you proved me wrong. Really well done!
This is the BEST informational light maintenance video out there. Thanks for the content!
Came home to a light strand out in the center of our tree. LightKepper Pro made for a quick repair identifying a faulty socket. Thank you very much! Merry Christmas
Thank you so much big help. I’ve repaired my lights. Savings $$$$$
They need to update this for LED lighting.
Great video though.
Great Video kudos, had a light set that was driving me crazy! Half way through It I had the answers and had it fixed in no time, I saw the commercial and ran right to Meijers and got one last night great buy money well spent!

Still watch this great video with Lights Out on strig decorations.. has helped many times!
Awesome and informative! Thank you!
I bought two of these with some other goodies for 5 bucks at goodwill, What a score these are great.
Very good tutorial! This thing is legit. The clicker usually works or the voltage detector points you to the problem area.
Excellent video!! THANK YOU!
It’s that time of year again. Time to curse out my strings of lights.
At least your lights didn’t die AFTER the tree was lit, and decorated like mine last night. Half my tree is lit, and now I have to take it apart to fix it!!! Yay me
@@candie1230 I told my wife I'm not buying any more.......done.
12:38 start of devise instructions
THANK YOU FOR YOUR VIDEO I LEARNED PERFECTLY A GREAT VIDEO GOD BLESS YOU I FIXED 5 series of light bulbs in a short time
Awesome tool. I have a prelit tree and some 30 to 50 lights went out. I thought I'll spent 10 minutes taking the string of the tree to make it easier one to fix. After trying to shunt the first bulb I noticed one flickering along the string of dead bulbs. Once that was replace 80% of the string light came back to light.

Thanks again for existing @Lightkeeperpro! Mind blown 🤯 again and again ✊

I've been using one of these for the last three years and it's been phenomenal. So many light strings saved by it. I've even brought pre-lit trees back from the grave. I'll write a more thorough review at some point but thank you for making yet another holiday season bright.
I had forgot to mention that my wife had thrown the three that didn't work into the garbage and I hate that being the type of person I am I like to try and fix things and that got me wondering if there was a tool, and that brought me to TH-cam and eventually your video. I saved it so I can watch and share it.
The entire top section of my tree isn't working but when I use the voltage detector, I hear a continuous beeping in some sections and a slower beeping in others. There isn't any silent section. Do I replace all the slow beeping sections instead?
I found the information on the shunt to be enlightening. I knew about the shunts and understood fundamentally how they work. I always assumed they were some sort of fancy wire. Nope. Just aluminum and utilizing the aluminum oxide layer as the insulation, clever.
We had two fancy wall decorations that didn't work. I was going to throw them out. Used the instructions from the video, canniblized one of the two decorations, and got one to work and one for spare bulbs. One's better than none,, so we're good for a few more years.
The LightKeeperPro is a good tool, it does have a learning curve this video helps with. However, I don't think it could have helped the light string the squirrels got to the other year.
Great information video but at @20:01 his comment is a bit misleading during the voltage tester instructions.
He says you can “identify the wire that has current flowing through it, and one that does not”. This is not technically true because neither wire has current flowing through it. In fact, if current was flowing through any wire, there would be a complete circuit and you would have light.
What he should have said is “you can identify what wire has a voltage and what wire does not”. In reality, the voltage is interrupted by an open circuit, therefore on one side of the lamp you have a 120v voltage, and on the other side of the lamp, that wire would have no voltage. In other words, because of the open circuit, no current is flowing through any wires.
What does it mean @15:03 "Release Lamp Locks Prior to Using"?
Very helpful video. Thanks for putting it together. May I suggest that you add an index in the description to make it easier to reference specific parts of the video in the future please?
I'm a retired mechanic and use this every year, It is an essential tool made for the job.
Pity we have to fix this cheap junk made in China by prison slaves and child labor.......
Stephen Shanko, Normally I would be saying the same thing,
The problem is if you were to make a quality string the bulbs have a limited life,
In a short time you are going to have to replace all the lights in that string in order to preserve it,
Or chase the last of the aging bulbs as they fail,
It only takes a few bulbs out to raise the voltage, this begins a cascade on the older bulbs.
But I understand I have led roof lights 5 years old while my reindeer lights corroded in one.
A nce adjustment of my problem. I developed much of the plans but
1) 20 pulses.. I was told 3, I used 5 or 6!!
2) I have a wired angel about 5' x 7' who has the metal conduction of the signal. The mini bulbs are next to each other.
Over 30 years, I have had to pull the bulbs and test them as I thought the signal was carried by the steel frame. It has been a challenge as all worked until I hauled the angel to the location. The left lobe of the "skirt" is dead. Concerning the conduction of the signal on the steel wire, it has been a bear. I appreciate your lessons. I found the "Lightkeeper" back then, then about 10 years later I came across the Pro.
I just bought this thing already thinking on the disappoinment... BOY WAS I WRONG...
THIS THING IS PHENOMENAL!! IT REALLY WORKS!!
olliefraga, I found two of these and two other little testers in a bag at goodwill for 5 bucks, Boy am I glad I found it!
Great info, although I would have preferred a bit faster reading. Got any related information on LED light strings?
Ok I’m trying to fix a prelit tree and here is my problem. First the strand doesn’t jump nicely from one branch to the one next to it, they are all over the place. Then there are some bulbs with an extra side portion (looks like a sidecare) with what I’m guessing is a ground wire. These then have three sets of wires moving off them in different directions. So following the voltage gets a bit tricky.
My problem is that as I move along the wire I get a strong beeping but then it falls off and does a double beep. Not silence and not continuous beeping. Does that mean the voyage is low or what? I have replaced many of the bulbs but to no avail. I actually had one set that came on while I went to purchase your product. Why would they do that?
same exact issue here.
Thank you for the detailed tutorial on troubleshooting and repairing this frustrating holiday issue. Your explanation on how when a light burns out but the shunt works that the electrical load is spread out over the remaining bulbs in the circuit and that it is important to replace it immediately to preserve the remaining bulbs, otherwise they will burn out at an accelera
ted rate (The Cascade Effect) As I was beginning the process of finding the problem areas, I quickly realized that entire lengths were actually burned out and 3 @40 bulb sections would need all the bulbs replaced.....grrrr. These lights are on an artificial prewired tree and can't just be laid out on a table top to work on.
My bulb tester doesn’t work. How can I fix this? The fuse tester works, its just the bulb part that doesn’t light any bulbs. Please advise. Thanks!
Very good video...great information
Very good explanation. Learned a lot About how the light sets are constructed and the techniques of using the light keeper pro. Thanks so much for taking the time to make this video
I have the light tester and the tester beeps at every bulb yet the strand remains as non working?
Same here. I’m getting very discouraged.
I have use this for a few years and i have always had a bulb issue until this time. I was about to pull the section of lights off, but you talked about switch the polarity of the plug.... this helped! Found a socket that part of the wire slid out and wasnt contacting the bulb.... and BAMM! The voltage detector kept making me look here... and well that is how i found it .... thank you :)
Lets say it lights up but doesn't beep when checking it? We think one of the wires might be loose but idk
It does beep but only when repeatedly clicking to check so strange and it wont keep beeping even though it did initially
How do you change the batteries? I can't seem to get the new ones to fit.
I changed all the faulty lights on the area that wasn’t lighting up. When I identified the problem using the lighter they all came on but then within minutes all the bulbs I just changed burned out leaving the old black residual on the original bulbs previously observed. I also identified an area on the wire that was not picking up on the voltage tester. I tried to reset all the lights on those isolated areas but still nothing. Help!
Yes, It really works!!!
The 35 minute point should be at start of video to save time
The problem is that 10 years later, after this video was made, they've changed the net lights. Now, there are hooks at the top of the bulb to string them together. There is no way to insert the bulb housing into the trigger pull. It doesn't fit.
Where can I find the "international version for 220volts" version you talk about in the video? I couldn't find it mentioned anywhere on the web.
Hi Giorgio, you can purchase the international version through our website at: lightkeeperpro.com/purchase-now/
This video is terrific. I wish I would have seen it years ago, and my pre-lit tree would have probably lasted much longer. I am working with the voltage detector and only get a few quick chirps, rather than a continuous signal. Do I need new button batteries for the set, or is there a different problem?
Hi Matthew, I would recommend viewing our "Audible Voltage Detector Part 2" video on our LightKeeper Pro site as it might be able to assist further with this feature. You may just want to jump to the other side of the unlit set section as depending on the polarity of the set, you should get constant beeping on one side or the other of the unlit section. If you have any other questions, please don't hesitate to give us a call at 888-858-2548 to speak to one of our technicians as they are available 7 days a week between Thanksgiving and Christmas.
Got halfway through and just ordered a prelit LED tree 🤣
Hopefully it still works next year. So far my experience with LED lights is that they last 1 season.
So far I've purchased about 8 led light sets and none have lasted more than 2 years of light use. Oh by the way, my prelit tree from 2001 is still working thanks to the Lightkeeper Pro...although right now I'm watching this video again because one stubborn section is burned out and I have yet to inspect all the new bulbs I replaced in that section to make sure the wires are making good contact with the socket. The voltage detector seems to activate along the entire strand. The other thing I do to keep the new bulbs lasting longer is I made my own dimmer switch attached to an extension cord used solely for the main plug for the tree, and I turn down the voltage going to the entire tree. It's fun because I can choose to illuminate it very dimly like candlelight in a dark room and it's more aesthetically pleasing than blinding full brightness. I can also turn the tree on and off with my foot on the dimmer switch, no need to bendover.
Can you recommend a quality supplier of condesent mini bulbs, please?
Thanks for this video. Is it possible to make it in french? It could be very well. Thanks again
Hello, we do offer a French video on our website at: lightkeeperpro.com/francais/
well I've watched a few different videos on fixing the light set. I was able to fix one right away, I've learned a little about electricity...now when I tested the light bulbs they don't lite on the lightkeeper...am I doing something wrong? 'Q...if the socket is damaged cause it doesn't have a replaceable fuse, is that it for the set? The other half I got to work? What do I do?
Nnbnhj Jon
If only half your strand is working, did u try testing the fuses? One of them may be out. (I was able to fix this same problem that way on one of my sets)
Sadly this tool is not usable with net lights. Maybe it’s time to up date the design. I will have to return the one I got
Can I borrow a pen please….
I purchased the tool and used it to fix the Christmas tree - a section of the tree didn't operate. I found the dead light bulb (2.5V incandescent) finally. So, I took out the deal bulb, tested it and made sure it was dead. I replaced it with a new bulb, tested it using the light keeper pro, and plug it back to the socket. After I switched on the tree, the section worked but only for less than one second. Then took out this new light bulb; it is dead. I took out every incandescent bulb and tested them one by one. They all are dead. What could cause the problem? I am going to replace these 50 light bulbs and doubt if they all will be gone within a second.
Boa tarde!! alguém sabe me informar onde comprar um desses ?
This works if you can find one buy it and learn how to use it you will be amazed 😮😅😅😅😅😅😅
How do you turn on lights without remote?

Hi Frank, I'm not sure I fully understand your question but you can reach out to our technicians at 888-858-2548 to see if they can be of any further assistance. They are available 7 days a week between Thanksgiving and Christmas. Wishing you Happy Holidays!
I want a version of this video where my millennial ass gets frustrated with my Christmas lights and my dead grandpa's ghost yells at me for just saying I'm buying new stuff instead of fixing them and then I'm haunted by the ghosts of string lights, oversize decorations, and pre-lit christmas trees. I wake up and find a lightkeeper pro underneath my half-lit christmas tree and I use it to repair my decorations. Outside, snow is falling.
That's all good and well when you have your lights set on a table but when the damn thing is wrapped and tangled on the those fake trees, boy, you will be cursing everyone for hours.
The only way is the untangle the mess and stretch the lights set, to be able to find where the problem is.
Thanks, dad(s)
Anyway to find empty socket on prelit tree.
The instructions were good up until you fix the brass contact. I did everything to the letter, but the brass contacts would not remain in their channel. This is glossed over like its a piece of cake. In the meantime, I'm still trying to put these in their channel and they do not want to stay put. Now i have to find another video that might address this issue (not likely). Pretty disappointed in the video.
Same here. I cut them out and spliced the wires. I’m not an electrician so will probably burn my house down. Lights still don’t work.

Invest in a living tree outside
OK, I have a set of blue icicle lights that don't light at all. I tried the quick fix method, No luck. I tried the Audible Voltage detector and it beeped all through the strand. I did try the Quick Fix again and still nothing. I did put new batteries in the unit. ... ANY SUGGESTIONS???
I've been having the same issue on a strand of lights & after carefully rewatching the video, I believe that we may be getting a false reading with the voltage detector due to holding it too close to the wire, hand interference, or not using it to test near the glass of the bulb. Gonna try again & see how that goes...
So basically, if your sets have seen 4-5 christmas seasons...they're ready for the trash.
The bulb puller you demonstrate here does not fit my Balsam Prelit Tree bulbs. The plastic base is too large to fit in the hole of the tool. I have yet to find an easy way to pull out these bulbs.
Very good video, me if they would show me how to build a loft in my garage
Just bought this product today. Didn't work for me. The bottom and top of my tree is working but the middle is not is not. The lights were already on the tree when it was bought new. With the top and bottom working and not the middle; this tells me that there is current going through the tree from bottom to the top. I watched this vid and about 5-7 on their website www.lightkeeperpro.com but nothing has worked. Changed all the burnt bulbs. Tried the trigger thing, and also tried the button on the top. Pointed the gun at the 1st bulb got nothing, I changed the polarity and got the beeping sound. Tracing the wire, I would get the rapid beeping sound on one of the lit bulbs then about 4-5 lit bulbs down the line, I would get nothing, even though it was lit. Trying again, I would get the rapid beeping sound on one of the lit bulbs then about 4-5 lit bulbs down the line, again nothing. Same thing would happen at the top of the tree as well, still nothing,,,,
Get to the point already! Dang, this video plays like an advertisement and has a lot of rambling on about absolutely nothing.
Spend $13 and buy and actual LED strip from ebay or Amazon. Not those janky overpriced same-as-the-old-ones strings with LED bulbs. Get a ribbon strip. Its a solid strip that NEVER goes out like ALL stupid POS string lights do. You get a remote and a variety of color and pattern options. Once you string it inside your tree you don't see the strip but the lighting is amazing. This isn't 1900, its 2020 and you don't ride a horse to work. Your great grandfather's Christmas lights should have been obsolete 50 years ago. Stop the insanity and embrace that which is better in every way. Nobody should have even had to make this video. Your LED strips will last 20 years without a single light going out. Dollar for dollar the value is vastly superior. You don't have to ruin your Christmas before it comes, haggling for hours with crappy string lights. If you do, its your own fault. Skip this video, and jump straight to the video titled "Why do I make life so hard for myself?".
One kink in an LED strip shuts off the strip from that point on just like a kinked garden hose.
Who is gonna spend this long time?
Watching at 1.75x speed 😀
Move your business to America and quit selling out your country .
Other than that, you did a fantastic video.
How do you know you have an “operational outlet?” You make it sound like that’s so obvious.
Detailed but SCATTERED (unorganized thoughts) and do not cover even 50% of how to fix lights.
Here's a better video in one second: BUY LED STRIPS.
Everything this video discusses and everything it misses are all remedied forever by doing this one thing.

They don’t make repair videos like these anymore 🫤
