I have a 1999 Mustang GT Convertible. A couple of nights ago while driving home from work my headlights blinked on and off. I thought this was weird but didn't think much about it.

Tonight however, my headlights went off and stayed off while driving home from work at midnight. But here's the weird thing...

Both my hi beams and low beams both would not work. But if I pulled the switch back to use the "flashers" the highs would come on and stay on as long as I manually kept the switch pulled back the whole time. If I just used the high's normally nothing worked. How ever halfway home my lights popped back on and magically started working again.

My fog lights, running lights, blinkers etc.. all work just fine its just my headlamps.

I checked all the fuses. They seem fine. Any ideas?

 

It sounds like your headlight switch has gone bad. I would go to a local auto parts store and buy one before doing anymore night driving. Safety first!
