Head light problem

I have an 88 Wrangler and my head lights cut out every now and then when I have them on bright. I can get them to come back on by switching them to dim. They have only done that to me twice. I have put the lights on bright and tried to wiggle wires and shake the jeep, but I can never get them to cut out.

Re: Head light problem

I had a problem like that before. I just put in a relay since there seems to be some sort of circuit breaker system that overheats and causes it to turn off your lights...atleast thats what Ive been told....either way after the relay everything is fine.

Re: Head light problem

Little foot is right, it is a circuit breaker that overheats and shuts off. Mine use to do that a lot, I have since put in relays for both of my brights and my regular lights, I also ended up putting in a relay for my off road lamps on my bumper also. The relays noticeably increaced the light output of each light.

If you need a schematic I'll try to whip one up for you.

Re: Head light problem

It may not be the relay. I had this problem as well, but found a bad connection going to the relay, causing the aforementioned problem. Check the wiring under the hood and check all the connections before replacing anything.

Re: Head light problem

I just had the same problem with my 89 YJ. It was the switch itself. It is very easy to fix. Just remove the switch from the dash and wiring harness and you will see all tyhe tarnish on the connection. I bought some electrical cleaner and some emery boards(finger nail type), cleaned it up plugged it back in and it was fixed.

Re: Head light problem

They only shut off on bright and they act like something is overheating. What do you mean you put in a relay. do you mean you replaced the existing one or did you rig something of your own.

Re: Head light problem

what I did was just get the wire that goes to the headlights and put a relay there....then the relay would take up all the duties instead of the factory wiring. Since I had installed high output headlights I also threw new wiring from the relay to the headlights if not I probably would have fried the stock(thin) wiring
