Headlights drop out on high beam

[redgum78]

Anyone suggestions as to why my 73's headlights drop out on high beam? Low beam is fine. High beam after 10 or more minutes blink out then come on again after about 10 seconds.

The circuit breaker inside the headlight switch is going out....you need a new headlight switch

Ah thank you.

I thought it seemed like some sort of thermal circuit breaker but I couldn't find one. I didn't even consider that it might be in the switch.

Don't leave out the dimmer switch in this scenario, I've had the dimmer switch be the culprit in a case like this...twice, to be exact.

you could take the load out of the switch by adding relays, the switch then only the trigger for relays , main juice supply straight to relays and headlights, fuse it and your good to go , you wont ever have this happen again, no dimming of lights once other accessory's turned on either

I think I will do this as well. I was just looking at the wires and although they are in fairly good condition they don't look very heavy gauge. I will use it as the switching control for a decent relay then I can up the wattage of my bulbs a little as well.
