1978 Super Sport with 6,000 miles. Low beam was out when I bought it but high beam worked. I bought a new head light and installed it but did not install it in the bucket while I tested it. Right off the bat the low beam works but I notice a little bit of smoke inside the glass so I immediately switch to high beam, which works, then shut off the ignition. When I turn it back on, no low beam, but when I jiggle the connection it comes back on for a bit and then nothing (high or low). Glass now full of smoke. Connection blades look good. Tail light and turn signals work OK. Fuse looks good but what would cause enough over-voltage to burn out the headlamp elements? I went through the electrical threads in The Garage and didn't find a similar topic discussed.
