hey guys. so i turn on the truck today and everything is fine but then i notice my right front light is staying on.. even though my lights are off. i even turn the truck off completly and its still on. any suggestions on what is the problem..? im gonna go check some things and come back in a bit but yah wierd for only one to do this

 

well i drove home from my gf's and once i parked it was fine now. goes on and off fine like normal.. i checked all the cables and snugged up all the harnesses and whatnot but who knows what it could have been now.. hopefully doesn't happen again while im out somewhere ..

 

headlights are wired in parallel to each other, id check out a wiring schmatic, cause if the headlamps are Switched ground, as in the ground wire for the lights is run to the switch instead of the switch on the positive side, then from there you could have a short before the switch, first thing that came to my mind if the only the right lamp stayed illuminated, check out a wiring diagram first however

 

If you have the delay option: If you turn off the ignition before turning off the lights they will stay on for a timed period. Why only one would stay on I don't know.
