Is anyone running LED tail Lights on their truck?
I'm looking into adding them to mine.
There are several styles (and price ranges) out there....
I have found them for just under $100 to over $200 a set.
I'm looking at normal looking red lens, not the clear or smoked...

 

 

I replaced every incandescent bulb with LEDs on the entire truck for less than 1 of those one piece tail lights, just another option for ya

 

I believe the "interference" is when there is no resistor built into the light kit and the result is a really fast blinking turn signal as if you have a burned out bulb. The built in resistor creates the proper resistance in the light circuit so that your turn signal blinks at the proper rate. If there is truly some other interference with other truck systems, I want to know about it as well because I've also been looking at some rear LED kits.

My personal favorite is linked here...

+1. This is what I did also.


There are flasher relays made specifically for LED blinkers also. https://shop.advanceautoparts.com/p/...ep27/5060001-P
LED bulbs with resistors built-in are more for vehicles that have blown bulb detection and usually cost more. Our trucks don't have blown bulb detection.

 

Can you explain further, or point me towards a thread where this has been discussed? I don't want to waste time with a kit if it's just going to raise H377 with either my trans or TC. Perhaps some type of shielding can mitigate the interference?

 

I've never heard about problems with transmissions from installing LEDs.....I think sometimes you have to install some sort of resistor to keep the lights from flashing too fast.....

 

 

I don't get the whole resistor thing. Buy a $3 resistor and add it to the wiring, pre-socket to every place you change to a LED just so you don't have to buy a $12 electronic flasher to replace the old filament/spring operated flasher. That's not to mention the heat build up of the resistors and cut insulation. The wiring in the truck will be better off pulling less power for the LEDs. Especially if your trailer is all LED as well

 

Thanks, John.

Wesley, you bring up a good point. My comment was more in relation to getting LED bulbs which have built in resistance, and not in cutting the wiring to add specific resistors on each circuit. The issue also only relates to the flasher bulbs and not all the other bulb locations.

 

I took my stock lights, cut open the backside and mounted one of these in each side. I changed over to an electronic flasher to get the flash rate correct, other than that there has been no issues for 8-10 years. I used a combination of hot glue and silicone to seal up the housings around the oval led lamps. Heck of a lot cheaper than most of your other options.

to correct this all you need to do is one of the following

1: install inline load resister

2: install LED compatible flasher

as for the PWM that may be a possibile issue on some trucks that are from roughly 2000 or later (I ran LEDs on my mustang on all lamps and had no issues and that was a 2004 mustang)

 

On the OBS (94.5 - 97 year models) this was a problem. LED's without the resistor did cause the torque converter to unlock as if you were stepping on the brake peddle. PCM supplied a small voltage to the brake lights always and think with the resistance of the 3 brake lights it was around 3 volts. If one or more lights burnt our that voltage would go up to 5.0 volts causing the TC to unlock, thinking you hit the brakes. I don't have a clue why Ford made this design, On the OBS forum many have reported with key on and lights off the brake lights were on at visible (led) very dim,.

There was a technical bulletin on this issue but can't find it. In any case Ford probably fixed the issue on the 99 - 93
