LED headlights
I have a 2015 GMC Sierra 1500 Denali with of course poor stock headlights. I replaced the headlights with LED'* and instant better light. So, I had planned to take truck out on highway to adjust lights but the left light went out. The light seems to work without starting the truck but after two seconds after starting the truck the light goes out. Anyone have any ideas? Thanks

Did you any resistors?

Seems to me most of these require a resistor to satisfy the BCM or they may not work correctly and may cause other things to not work correctly. Does the cruise control work OK?

Hi, yes my cruise works fine. I switched lights from one side to the other and that same light goes out in the other position so I am taking light back to try another one.

So I put in new headlight and that appeared to be the problem. Both headlights working now, possibly bad driver for headlight.
