driving at night has sure become entertaining:eek:

the dimming, on and off is not consistant.

i will check all grounds.

i have heard wiring in relays for the headlights will improve performance and decrease pull on the system.

how do these wire in?

stock wiring, brake lights work, running lights work, turn signals work, turn signal indicators work, high beams work. only issue is the headlights go off and come back on as the please, even at a stop or smooth road.

Bad headlight switch behind the dash. This has happened to me in the Bronco as well as my '65 Mustang. Headlight switch both times.
