1990 Ford Mustang GT Question: intermittently flickering headlights
my headlights will go off for no apparent reason and come back on when they get good and ready. Seems to be no pattern. Is thia a headlight switch, fuse, circuit breaker, high beam switch, fog light switchproblem or what. It doesn't seem to matter if the fog lights are on or off. Kinda scary at 70 on the interstate. - mustangguy
