Headlights Problem

[George3]

My headlights will simply go out (usually at night, of course!!!). Sometimes they work properly and other times not. I've taken it to a mechanic who kept it for two days, did various tests, etc., and found 'nothing wrong'. The next day the same problem happened. Can someone help me with this problem? I can't do daylight driving all of the time! Thank you!

Sounds like a short in a wire somewhere or possibly a bad relay. I would play with the wires going to the headlight and see if you can get them to turn off with the car just in the driveway. If you can find where the short is you can fix it. If you can't find the short or find some way to recreate the problem, it might be the relay.

I have to agreewith Daox a short somewhere as listed. But some time it can be in the bulbs (filament)them self starting to burn out the looses contact when it cools off makescontact work till it gets to hot breaks contact again.
