Thank you! At the auto parts store they said it would be too complex for a non-mechanic. I just followed your directions and it worked like a charm in under five minutes.
man you're a life saver, not only you showed me how easy it is, but also i had NO idea the cracked dash was part of their extended warranty! i was FURIOUS to find out the dash started cracking and thought i needed to live with it, but man thanks a lot! i called the fucking Stealership, gonna get them to do it asap!
It's funny how many stores tell people to tear aprt their engine compartment to get at their lights, when they are right there accessible from beneath.
Thank you so much! Who said a female can't work on her own truck...lol... (Thanks to your video). It helped me out a lot! Plus, didn't know about the dashboard. I will definitely inquire on it.
Thanks to you I saved myself $100 by not having to take my GX to my Lexus dealership where I live to replace my turn signal on the left side. Also, did you know that your dash is under extended warranty? Lexus replaced mine for free
Yes, Lexus replaced our dashboard 2 years ago under this special warranty extension. The program ended 6 months ago however, and lots of people still on the waiting list from over a year ago, just waiting to get their cracked and melted dashboards replaced.
I don’t know how you guys were able to reach the bulb from below - it’s so high off the ground, I couldn’t even see it, much less reach it. ...but I didn’t give up! I was able to easily remove the plastic cover from under hood ( mine fits securely in place w/out the plastic screws). It was way easier for me to see, reach, and replace the bulb in a couple of minutes. (and then put the plastic cover securely back in place) Your video was very helpful with at least knowing what to look for. Thanks!
Thanks for the fine instructional video. I replaced both the front and rear turn signal bulbs on my 2004 Lexus GX470 and installed the load resistors as you described. No flicker or signal errors whatsoever. So try and figure this. Most people probably wouldn't have even found this "issue". To check my work I left the hazard lights flashing for about five minutes to make sure all was good before remounting the rear tail light housings. I also wanted to see how hot the resistors really get after hearing all the warnings. Checking the rear drivers side first, the resistor was as cool as the weather here in NY. Mid forties. It was cold. Checking the rear passenger side, it was screaming hot. I've had them in over a day with absolutely no issues at all regarding the turn/hazard light operation. They work perfectly. But I can't help but worry that something is not right. Any explanation for this. Please advise
Gene, only one of your resistors was conducting, the screaming hot one. Since you were running in flasher mode there was enough current being drawn by the other bulbs to have them flash at a slow rate. It is dangerous to run these resistors without suitable heatsinks.
Thanks Jeff, Really like this video. If I change the rear bulbs as well do they need a load resistor as well or is the front resistor sufficient since they are on the same circuit?
That is a really good question. We assume you would have to use a resistor for every bulb, but we have not tested this theory out yet. You might get lucky and maybe the resistor you added there will be enough load for the whole left side or right side circuit, we just don't know the exact load it is looking for.
Hello Jeff, I own the same vehicle and am in the process of changing over all original bulbs to LED's. I realize that the load resistors are required for the turn signal lights but do I need the resistors for the brake lights also. Can you recommend bright, reliable bulbs for this project. Thanks for taking the time for putting up this instructional video.
Fast blink is caused by your resistor not making good connection with the LED wires. If you don't get it right, and the ECU thinks the load is different from what it should be, it will blink fast.
Hey how have the LEDs worked out so far? I want to install them on my 08 GX470 but I'm just afraid of the bulbs melting the housing due to heat, or the resistors causing damage because of heat as well. Have you had any of these issues?
Thanks you for ur video and its informative. I have a question that changing the LED signal light bulbs with the resistor will save the power? (does it consume low watt than traditional bulbs?)
Sathasiviam , no the resistor addition makes the current drain the same as the bulb. That's how you fool the flasher by drawing the same current as a bulb would.
I would much rather modify my turn flasher module than wire in all of those resistors and defeat all of the energy savings of having LEDs. I’ve done it in a 2007 4Runner and is the same process for GX470.
LOL, it's not like you losing any energy, or spending more on fuel for the lights. We'd rather not have to go through this process either, but these turn signals blow about every 6 months, which stinks, so the switch to LED was an easy choice. Also in model years of Lexus after this one, they have a new ECM that detects LED bulbs, or they are not affected by installing LED bulbs.
thanks for the post. I have a question. I am in the process of upgrading all the stock bulbs, interior and exterior, in my 2004 lexus gx470 with led bulbs. which new led bulbs require the use of the resistors.
I see how ur changing the bulb to led. The interior of my car has tiny bulbs in it.. how can i get leds for them.. and whats sizes are they.. and what are they called? Is there a converter? Where base is the circle metal part and stick a led pin in it
@@carbuying thank you for the follow up amigo. I just bought some decent resistors that look almost OEM from VLED. Gonna tackle this weekend. You are a gentleman and a scholar
What year is this GX470? Mine is a 2005, and the manual says I should be using a 4157, but several database list the 1156 for my model year, which is what yours is in this video.
They should come out the same way, figure out which bulb, grab the housing from inside the bumper and twist counter-clockwise. This will expose the bulb. Mine are wedge bulbs that pull straight out.
Nonamus Gaming If the LED light is blinking too fast it means that when you attached the resistor you didn't pierce the skin of the wire enough so it did not crimp and make contact to the resistor wire. You need to undo it and try to re pinch it and make sure that the connector makes contact and bites through the insulation of the wire. The LED is blinking faster because you have not successfully tricked the ECU into thinking that there is the right amount of resistance on the line.
I have heard people complaining that they bought LED bulbs from sellers who claimed they don't need the resistor. Go back and check online reviews of the product you bought and see if others complained of the same thing. I remember thinking at the time that the sellers were lying to you that you don't need the resistor. Older Lexus models, the ECM needs to see that resistor there.
First of all THANK YOU for showing how easy it is to get to the bulbs. But, this is dangerous as shown in this video for two reasons. The resistors first: The 50 watt ratings are achieved when the resistor is suitably heat sinked, these are not. They must be de-rated to only 35% of their stated wattage when running w/o a heat sink at 50°C (122°F) (35% of 50 watts is 17.5 watts. Since charging system voltage is 14V, (NOT 12V) these will draw 32 watts Doubling the rated power. tl,dr? THEY WILL GET TOO FUCKING HOT. Now, zip tie all the wires together with this hot resistor then see what happens. To the author of this video, please show us a video of your hand wrapped about this resistor with the turn signal operating, YOU CAN'T. The second reason: Those crimp style connectors may work well initially but they're not weatherproof and copper wires corrode and resistance goes up. I have personally felt one of these get too hot to touch connecting fog lights under the hood of a car. Don't believe me on the derating? Check the data sheet. www.mouser(dot)com/ds/2/427/rhnh-220018.pdf I just did this to my motorcycle and ran into this problem. I used a PC microprocessor heatsink cut in half, without it I couldn't hold the resistor for more than 5 seconds before it became too hot when the blinker was operating.

Thanks for the instructions, changed front right turn signal successfully (•‿•)
That warranty ended in 2017, we got ours covered in 2015, a $2500 repair.
Exceptionally Helpful! Your video saved be a great deal of time. I SINCERELY thank you!
Glad it helped
You really helped me out. Autozone was telling me that I needed to take the whole headlamp out.
It's funny how many stores tell people to tear aprt their engine compartment to get at their lights, when they are right there accessible from beneath.
Thanks for your video!! I just switched the light to a new one!!!
Thank you so much! Who said a female can't work on her own truck...lol... (Thanks to your video). It helped me out a lot! Plus, didn't know about the dashboard. I will definitely inquire on it.

I'm in northern US so no chance of my dash cracking. I am moving to south, though, so I'll be sure to use a windshield sun cover.
They replaced ours in October 2015. Program ended April 2017.
Thank you soooo much. I have a 03 and I'm going to do this as soon as possible can.
We are now searching for a used 2018 GX
Thanks! so much faster than taking out the plastic hood covers.
Awesome, we are so glad you found this video useful.

that's a quick fix

Thank you so much this helped so much and was way easier than all the other videos saying to remove the battery and stuff
Danish, awesome, glad to hear the turn signal change worked out for you. Congrats on getting that done yourself!
Thanks Jeff, Really like this video. If I change the rear bulbs as well do they need a load resistor as well or is the front resistor sufficient since they are on the same circuit?

I’m thinking of getting a switchback led turn signal with a resistor on my dads GX, hopefully it would work good
Looking to buy a new GX altoether!
Hello Jeff,

I realize that the load resistors are required for the turn signal lights but do I need the resistors for the brake lights also. Can you recommend bright, reliable bulbs for this project. Thanks for taking the time for putting up this instructional video.
Yes, all LEDs need these resistors to trick the ECU into thinking it is the correct bulb. This is load matching.
Thanks, that was easy. LEDs work great except I have a fast blink. I guess this is the result of less resistance. Hazards work normally.
Fast blink is caused by your resistor not making good connection with the LED wires. If you don't get it right, and the ECU thinks the load is different from what it should be, it will blink fast.
I had my dash replaced on 2004 4Runner. I was told it would be 8-9 month wait but was only4-5. FREE!
We waited 4 months
RH50 ~ I've seen people attach to PCB & wonder why board burnt. ( We all know why ;~)
Hey how have the LEDs worked out so far? I want to install them on my 08 GX470 but I'm just afraid of the bulbs melting the housing due to heat, or the resistors causing damage because of heat as well. Have you had any of these issues?
LEDs are still holding since we uploaded this video.

Same current drain, but resistor gets hot

Yes, all LEDs need these resistors to trick the ECU into thinking it is the correct bulb. This is load matching.
That’s called a turn signal bulb,right ? And what is the name of one directly below the turn signal call? Mine went out too.. thanks
That might be the DRL, Daytime running light, or park light
I see how ur changing the bulb to led. The interior of my car has tiny bulbs in it.. how can i get leds for them.. and whats sizes are they.. and what are they called? Is there a converter? Where base is the circle metal part and stick a led pin in it
We usually search on Amazon
Could you do another video for the replacement the headlights by LED ones for this car? Thank you.
Headlights are a real pain on this vehicle
Is your DRL still functional
Yes, still works

Where did you get the thing on your bumper that says gx470 from? I want one
Chubby Llamacorn ,,,exactly my question too..Did he give you info where to buy it?
Are you talking about the GX470 that is stamped into the blue center plastic of the front bumper? it came that way from Lexus when I bought it.
What part are you asking about?
Jeff Ostroff yeah that bumper guard where can I find one?
Came on the GX470 from the dealer.
need to know how to replace signal light on 2003 Toyota 4 runner.
Bumper mount Beside fog light. Help please.
They should come out the same way, figure out which bulb, grab the housing from inside the bumper and twist counter-clockwise. This will expose the bulb. Mine are wedge bulbs that pull straight out.
Twist and shout!
thank helped me a lot.
Glad to help
great. video. very helpful
Glad help out,t hanks for watching.
I tried on mine, it blinks too fast.
Nonamus Gaming If the LED light is blinking too fast it means that when you attached the resistor you didn't pierce the skin of the wire enough so it did not crimp and make contact to the resistor wire. You need to undo it and try to re pinch it and make sure that the connector makes contact and bites through the insulation of the wire. The LED is blinking faster because you have not successfully tricked the ECU into thinking that there is the right amount of resistance on the line.
Were you able to use our advice to solve the fast blinking?
jeffostroff oh I didn’t put the resistor it said it won’t need it on mine
