Re: have a headlight issue

Probably not what you want to hear, but if you have original wiring I would recommend a complete rewire of the entire truck. I've seen to many nice rides burned up because of 50 year old corroded wires. At least rewire your headlight circuit to use a relay, and not run all the current through the switch.

Re: have a headlight issue

Check the dimmer switch on the floor. Many headlight related problems have stemmed from a faulty dimmer switch.

Agree. This was the culprit when I had headlight issues.
