Went driving last night and had to use my brights. All of a sudden, they went out (both of them). I hit the switch and my low beams came back on. So I turned the brights back on, and they worked again, for a minute and back off they went. So I was stuck using my low beams for that dark road.....My question is what would cause this....Wiring or bad switch?...

As a sidenote...the "Mustang" that lights up when the brights are on, also went out when the brights went out, and came back on when the brights came back on.....

TIA

Sounds like you need to change out the light switch. When it heats up the lights go out and when you let it sit for a while the lights work. right?

Yep -- high beam switch went on mine -- put a new one in and presto - no more problem.

It wouldn't hurt to do the headlight switch too. My 71 started out that way, then even went to turning lights on and off regardless of high or low beam. The $10 headlight switch fixed it fine. Now as I look through some of the wiring harnesses I have I see torched wires from the headlight switch. Better safe than sorry.
