Attention: TDR Forum Junkies Monday mourning Started the truck at 1 am with 36 degree temp outside and warmed it up until grid heater stopped cycling. Turned on headlights and proceeded on my way... . after 50 ft. of driving the headlights started to alternate between headlights and fog lights. 
Then I clicked the brights on and off and turned headlights on and off and back on. They worked fine for about a mile then started alternating between headlights and fog lights again... ... the on-coming car started flashing me back... What the heck is that all about !
My lighting is stock.
Anyone have this happen ?
