head light trouble

[nitevision]

after about 20 minutes my head lights go off then come back on and keeps doing it

anyone have any suggestions on what this could be

Sounds like the wiring is loose somewhere. Start at the head lights and follow the wires back. You might find an obvious problem. Check the foot low/high beam button, this might need changing. Or the lights pull **** is bad.

Are you using H-4 headlights?

Yah, it's usually the hi-beam foot switch

If that is a regular cycling thing, it sounds like a circuit breaker. However, if it is a circuit breaker, it is either bad or you have a problem causing it to trip such as a short. Circuit breakers are often the self resetting style that look similar to a fuse but have a metal cover.

Good luck,

The wiring diagram that I have doesn't show where the circuit breaker is located. Does anyone know where it is located? I looked at all the wiring, the dimmer switch isn't getting hot, nor is the pull **** getting hot. I did have a fuctioning light that had moisture in it, so I replaced it. Haven't checked it out yet. Thanks for your help.

If you are using your original light switch, it has a built-in circuit breaker designed for the original headlights (35WATTS). If you are using H-4 lights they are 85-95W bulbs, thus causing the switch to overloaded and tripping in and out (voice of experience speaking!) . If that is the case you can buy lower wattage H-4 bulbs in bright white, or wire a relay into the system and use the higher wattage bulbs. If your not using H-4 lights, then check the ground wires at each headlight.
