Over the past week, my headlights have randomly flashed on when I've turned off my truck. It appears to be the high beams since the high beam light on the dash flashes on as well.

Never had this happen before. Truck runs/starts fine and all lights work as normal. They only flash on while i'm turning the key to the off position. I dont know if it matters, but I do have daytime running lights on my truck. Any advice or thoughts?

 

I would pull the plastic steering column covers off and check all the wiring in the column for a short. That would be the best place I can think of to start looking.

 

That sure is an interesting one.
