Headlight Issues

[anthony0069]

If anybody can help id appreciate it. I drive a 69 gmcand Ive had issues with my headlights for a little while but now when im driving i turn them on and 5 secs later they go off. I dont know if its time or the switch but i press the high beam switch on and off repeatedly and eventually they com back on, only to go off again. Does anybody know the solution for this? Could it be a grounding issue or a loose connection?

in the headlight switch there is a circuit breaker. It sound like its tripping. You may have a shorted wire in the headlights or a bad light switch.

could be ground, could also be loose or corroded connections. I had a similar issue with my 66 Chevelle, ended up being the high/low switch was the problem. they would go out and if I banged on the switch they would come back on.

At first the low beams wouldnt work but the high beams worked no problem. Now with the highs messing up is it safe to say it wiuld be a switch rather than a shorted wire? Also before this issue when lights were working it would take passenger light a moment to come on like it had to warm up or something.

i'd remove connections from dimmer switch and check the wires fir fraying and clean all connections/// a new dimmer is about $5
also remove the connections from the light bulbs and do the same thing check wires clean connection/// the first thing to do with 40year old electric circuits as just lookin at them does nuttin
