Getting out of my truck this morning the DRL LED was flickering after it turned off. Anyone ever seen that before? It was repeatable so every time I turned off the truck (or just turned the lights on and off) the headlight would flicker as it shut down.

Any ideas?

 

Does it flicker when running? Maybe loose connection in there somewhere. Would require baking the light apart to check for loose connection an I'm not sure about replacement parts. They aren't designed to be repaired. Replace if broken.

 

OP, is is both headlamps or just one? If only one it could be a ballast starting to fail.

 

I decided to do a little test. I went in and reset the BCM (that had fixed an issue with the power step before) just to see if it could be something weird like that. Lo and behold, that fixed it.

 

How did you reset the BCM?

 

Yeah OP, what Taggart said.
