(nato member) comletely rebuilt suspension with additon of caster camber plates lowered with mustang springs painted candy royal blue next up is increase of horse power by any means possable, (second place is just the first loser)

I sent you a copy of the headlight circuit. Sounds like a bad switch or loose connection.

Do they both flicker at the same time, or just one flickers, or they both flicker, but not at the same time? If they flicker independantly, check the fog light to harness connectors, or the bulb grounds. All that grounds the bulbs is the little spring clip that holds the bulb in. THese can get corroded.

they flicker together. they stay on for about 15min, then they start to flicker. could it be the relay?

I have a similar problem. When I turn my headlights on, everything is ok, but when i turn my fog lights on, the headlights and the foglights start to flicker on and off. The parking lights are ok though. They stay on. All the wiring is factory, no aftermarket switches or anything. I can't figure out what's up so I have been runnin with just the headlights all the time. Anyone know anything about this? Thanks in advance, Travis.

Man, why cant my headlights do that huh? I mean why did I go out and spend money to get mine to strobe like that! =] Well what I think is that there is some moisture in your headlight circuits, or possibly minor damage to the circuit itself. I mean im not an electrician or anything but it would make sense? But anyway, i would check that out. sorry i couldnt give you a deffinate solution =\.

That's the old circuit breaker problem. The headlight switch in the dashboard has an automatically resetting circuit breaker, and as it ages it becomes over-sensitive and having added current of the foglights causes it to trip - reset - trip again - reset...

What I did was install a relay on the foglights...and eventually the dims too. Simple fix, total of an hour, maybe. No more light problems.

What Liquid_force said....
