77 Headlight Problem

I'm trying to figure out a headlight problem. The headlights (low and high) are not working. I've checked the fuses and also the switch.

I read about a reset in the switch. I found a small pin w/ a spring. Is that the reset?

Any ideas concerning fusible links or the highbeam autodim?

Thanks for your help. -Andy.

Have you checked the dimmer switch on the floor? They can corrode and fail. It happened to my '79 Deville a couple of times.

It turned out to be a broken wire. All fixed!
