headlights went out

[67broncorebuild]

I have a 67 bronco, 302, and a mean green alt. My headlights went out, and they worked last night. I know the lights are good, and no bad fuses?????
I noticed the alt gauge needle moves irraticly, til i give it some rpms, then it mellows out and needle stays steadly charged.

I fix one thing, the next day i have something else to fix!!! Got to love it
Thank you!!!

fix your dimmer switch!!!

Either dimmer switch on the floor or the headlight switch itself. Dimmer switch is much cheaper to replace. $10 vs. $50

Check to see if you're getting power to the bulbs. A couple of months back, both of mine went out simultaneously. Come to find out, both bulbs burned out at the exact same time.

Bad grounding will give you intermittent problems and erratic flashing and such.

thanks, it was the dimmer. 1967 was a while ago, nice and rusty with the spring inside!!
thanks again
