Once last night and once tonight. Headlights turned off and back on. Last night I noticed with the highbeams. Tonight with low beam. Both times I had my 55 watt after market fog lights on. This has never happened since I have owned my truck ( 13 months). Headlight switch going bad???

Thanks......

 

That would be the most likely failure.

 

Putting the headlights on relays will keep that new switch from dying - and give you brighter headlights too.

 

do you have a schematic for the relays? thanks

 

There's excellent general info on adding relays here:
