@@Trafficlightdoctor , Perhaps check the output balance in the editing software and the computer to see if they are sending the same output to left and right output channels?
I have an aluminum LFE traffic signal with incandescent lights and 8" glass lenses. Despite being an 8" signal, it is pretty heavy, looks much heavier than that 12" poly LED signal!
If you want to see the inside of the led module, Technology Connections did a video called "Teardown of an LED Traffic Light Module" on his "Technology Connextras" channel, where he opens a smaller diameter one and gives some closeups of the circuit boards. Might not be the exact same manufacturer and model, but it gives an idea of the insides. He has traffic light LED modules in the backgrounds of all his videos for the past 6 years too :)
THANK YOU! That was me that asked to see. Being in Australia, it's interesting to see the technology used over there. There's only a small group of suppliers over here. Mostly owned by Tyco. Each "lamp" has lots of individual LEDS wired in little groups, so as some LEDS fail they look splotchy. Yes PLEASE to opening it up! Happy New Year!
I remember when daillight first came out, they were the worst for section outages in an indication a lot of municipalities left them for GE. I'm glad to hear about them fixing those issues.
Some 9 years ago i was a temporary worker at a company where they mainly place parts on pcb's and made special multi wire cables. One type pcb was for traffic lights. The lights did work on a low voltage and the current needed must a fixed value. They did say traffic lights, but i did see that kind of lights also in a railway signal just visible above a high wall when i go to my optimetrist.
Here in NYC we have a mix of the 12in light you are showing but most are the 8in light and all are made with cast aluminum and are on short arms not long like you have.
I have one in my garage. I use an Arduino mini with an ultrasonic sensor. When the garage door opens its green, as I drive in it turns yellow at 6ft from the wall and finally turns red when the car is 10" from the wall.
Could you do a comparison between the Dialight, GE, and LEOTEK LED modules at some point? My state uses all three and one of them IMO has the perfect diffusion to it compared to the others.
One thing is for darn sure is these Traffic Signals are Monsters since they need to easily be seen by a Variety of Drivers with a Variety of Vision Issues. 🤔👍
A little bit of semantic correction.. What you removed from the traffic light head is not an LED, it is a module, an assembly or an array. It contains multiple Light Emitting Diodes and circuitry to drive them from the supplied 120 VAC power. Since the device you removed & displayed contains an array of LED's & driver electronics within a housing, the proper terminology is "LED array assembly".
I have one above my bathroom door in my man cave/basement... Red means someone is in there with the door locked, yellow means the fart fan is on, and green means the door is open and the bathroom is free...
Two questions. First, when you change the LEDs, are they hot swapped or do you have to de-energized the single signal or the whole intersection. Second question, if that signal was for a left turn, is the arrow just LED or is there a cover over the LED to just show the arrow. Thanks
wouldn't mind seeing in an older incandescent model. I used to have a clear lamp marked with 'traffic signal' on it. had a metal flat reflector disc near the base, inside the envelope.
I could have used this video a while ago. I had someone absolutely insisting that traffic lights were all steel (a.k.a. rust piles to be) regardless of being told about the issues of precipitation exposure, weight for installers, and mass if it would fall onto a vehicle.
The main reason for going plastic is weight - metal lights weigh a lot more and at the end of a mast arm that's a lot of weight to be swinging around in the wind. Plastic traffic lights are much lighter, and with the LEDs weign practically nothing at all and are more easily handled during installation. And if disaster happens and they fall off, being lighter means they'll cause damage, but hopefully a lot less damage to someone who might be travelling underneath it.
I have a yellow Eagle Durasig in my traffic signal collection. It was in service in Michigan and came with an older set of Dialight LEDs that were installed in 2006. After nearly 20 years, they're still working great. I have a few different brands of LEDs in my collection, but mainly I use Dialight and GE LEDs. They work the best in my display.
Do you have any LEOTEK LEDs? Our state has a mixture of Dialight , GE GTX/VLA, and LEOTEK LED modules, one of them I dislike the look of as it seems like it has a hot spot in the center. One of the others has a "fuzzy" look to it, while the third one has a perfect smooth diffusion to it. Would like to figure out who made which.
Found a bunch of green & red LED bulb assemblies like those dumped behind a BJ's in NJ once ,all of them was in good operating order & no burned out or flickering LED's ,my relative wanted those hooked up in his garage so they went there, was a good find though
Since I am 73 years old I have lived through the transition from using incandescent bulbs in traffic light to using LED lights. These LED traffic lights contain a large number of small LED lights. The one problem I have seen with these traffic lights is that a group of LED lights in the enclosure will fail, causing an odd looking traffic light. There are two main advantages to these LED traffic lights. One advantage is that they use a lot less electricity than the old incandescent bulb traffic lights. Also these LED traffic lights last a lot longer than incandescent bulbs.

Why are some of the housings black and others yellow? In Michigan, yellow is used about 95% of the time, but the housings for crosswalks are mostly black, with an occasional yellow on older fixtures. In Florida however, black is common. Why the difference?
Traffic signals fascinate me and always did, there was a few intersections by me that used incandescent lights until mid 2021 sad to see an old set of lights from the early to mid 80's get turned over to LED and they don't flash at night anymore. They used to flash yellow ed, but later was changed to all red. The neighboring intersection does yet. Those lights were totally removed, gutted, replaced and were older yet. The original signals were from the mid to late 70's (yes these were incandescent as well, until they were removed in mid 2022) and the new ones were put in just last year (2024). These flash yellow ed, and it stayed that way for as long as I can remember.
Is there a standard that most municipalities follow regarding what percentage of the individual LEDs must be out/flickering in a single indicator before they replace it? Seems like some places are content with almost 60% of the diodes being out. Usually on the green indicators.
only use the sequence board at home huh ? why do i have the distinct feeling, you get the urge to use a sound activated one out in the field, and dance to harlem shake with the lights dancing with ya!?
Technology Connections (Connextras) already took the light module apart years ago - th-cam.com/video/hRbnK4cDXPY/w-d-xo.html - he's had those things in his background for a while now.
My left ear is now very informed.
I have no clue why the audio keeps recording that way! When I listen on my headphones it sounds fine.

Mate, you need a hearing aid for your right ear then.

He also has halogen ones in the backround

I have an AluSig aluminum light with incandescent bulbs. It's big and it's heavy. Surprisingly so.

I very much love the Dialight LED modules, love the pixelated design.

The main reason for going plastic is price.
Steel ones did need to get replaced much more frequently too. You could watch the rust streaks build up on them over time.
Have you ever installed the optically programmable traffic signals

@ I do, actually. A few weeks ago, I got a hold of some LeoTek bicycle LEDs from eBay. It’s the first bicycle signal in my collection.
Found a bunch of green & red LED bulb assemblies like those dumped behind a BJ's in NJ once ,all of them was in good operating order & no burned out or flickering LED's ,my relative wanted those hooked up in his garage so they went there, was a good find though

All my signal lights are incandescent so I have always been curious about the LED lights. I really hope you show the inner workings of the LED unit.
Why are some of the housings black and others yellow? In Michigan, yellow is used about 95% of the time, but the housings for crosswalks are mostly black, with an occasional yellow on older fixtures. In Florida however, black is common. Why the difference?

This video makes me want to ask---Can you make a video showing how an older incandescent signal gets converted to L.E.D.s? I see them regularly.
Is there a standard that most municipalities follow regarding what percentage of the individual LEDs must be out/flickering in a single indicator before they replace it? Seems like some places are content with almost 60% of the diodes being out. Usually on the green indicators.
Need one of those 🚦🚥 ,still got a old traffic light from S Korea 🇰🇷 & a older heavy metal US made traffic light with standard bulbs 💡, not LED
only use the sequence board at home huh ? why do i have the distinct feeling, you get the urge to use a sound activated one out in the field, and dance to harlem shake with the lights dancing with ya!?
Have a signal with a red led and the rest incandescent. Used the little green board in the video to control it.
I always thought they were made out of metal
Does the left or right turn lights work with.the ones on the straight lanes
do you have an online store for signals?
gee...now ya gotta go outside and put it back where ya found it...haha
Come on people get your friends to like this video we need to see the internals.
Wow I thought it just ran on magic lol !
This video made me lose my hearing in my right ear but Thanx for the knowledge.
ill remember this for the next time i steal a traffic light
Time to start disassemble
That's hilariously huge !!!
12 inch aspects.
You look tall, I’m guessing 6’1 so damn that traffic light is huge. I didn’t know they are that big
I need that light
Technology Connections (Connextras) already took the light module apart years ago - th-cam.com/video/hRbnK4cDXPY/w-d-xo.html - he's had those things in his background for a while now.
Those aren't the traffic signals I grew up with. Those look like junky toys.
300 likes we want the inside video
Why are American stop lights so giant when Europe is small and looks nicer 😮😅
I would have thought they would weigh more.
Those 3M housing I mentioned very much do!!
Have you put your hands on a 3M in the field?
Yes! Have a few at the shop as well that I need to bring home lol
Cool! Was there any 3M bimodal left or right turn signals?
Of course they are foreign made.
There’s no audio
Still getting Left audio only on this video. ⚠
Just researched it I think I know the issue and will try it. Strange that it works for me without the issue though!
U rock!!¡!!!!!!!¡
Cannot hear anything, and my levels are fine. Weird. Skipping this one
@@insevin7 yeah mic was set wrong it should work on a single device or a left earbud! I apologize for that!
The light's themselves look very cheap quality for a commercial product
