I ended up going with Xenonpro.com LED's. I purchased low, high, and fog and had them installed professionally. Everything seemed great until I was driving to work a few days after. This was the first sub-30 degree cold day. As I was driving I noticed the driver side headlight going out for 10-20 seconds and then coming back on. It did this a few times before eventually going out entirely. I have about a 15min drive to work with about 5min of highway time. After experiencing this issue a couple days in a row, we had a couple more warm days, 40+ and the issue went away. Next cold day, light goes out half way to work again. The passenger side never went out and both the high and fogs had no issues either. I tried turning lights on and off, no change. I had to turn the truck completely off and start it again before that headlight would come on again, sometimes only briefly.
Now the troubleshooting starts. I contacted Xenonpro.com and ended up getting new PWM modules and new LED. I first swapped modules, LED's with passenger headlight and the problem stayed at the driver side. The light and module that was previously going out on the driver side had no issue on the passenger side. Replaced the drive low LED and module with new, same issue. Swapped passenger and driver side LED and module again, problem still on driver side. For clarity, I had the same installers do all the work swapping the LED's and modules back and forth.
What's confusing to me is that this only seems to happen in sub-30 degree weather. If it's north of 30, NEVER have this issue. I ended up going to the dealer and talked to them about it. I took the truck in yesterday and they tapped into the wiring and installed a tell-tell light. When I picked up the truck last night the light went out as they pulled it into the customer bay. We popped the hood and verified that with the light out, the tell-tell light was off as well. I was able to observe the headlight and tell-tell go on and off a couple times before the headlight went off permanently. They pulled the truck back to see if they could determine where the power was getting pulled. They aren't yet sure if this is being cut by the computer or a connection issue. I'm supposed to bring the truck back in tomorrow to have them swap the pins under the dash to swap the circuit that the passenger and driver side lights are on to see if the computer then turns the passenger side off.
Curious if anybody else has seen this.
- Are you in a sub-30 degree environment?
- Is it possible the PWM modules aren't providing enough resistance? Would another mfg module work better?
Thanks!
