when i first got my jeep the lights would go out over a bump and then come back on after the next bump. i never intentionally fixed it but it hasnt done that since i took my dash apart to clean up some connections. im guessing it was probably a bad ground

When mine did that it turned out to be dust in the headlight switch. I pu,led the witch and took it apart for a good cleaning. Fixed the issue

Lots of things could be at play here, but first start with your connections on the back of the headlights. Make sure they are clean as a whistle- including the contacts inside of the plug itself. Any sort of corrosion or rust can make a bad connection and give intermittent power.

Also double check the crimped connections on the plug too, if one is frayed then it can cause an intermittent connection. Put some die-electrical grease on the contacts to seal them up from the elements.

All about that unibody life.

its most likely a dusty connector of some sort. mine did it to me too and i took the whole dash apart and field day'd it. never had an issue since. probably a good idea to do anyways.

Take your bulbs out of every socket. headlights, tailights, blinkers, ect. And apply dialectric grease it will save you . Not only in elecrical problems but your bulbs will last longer.

if you wheel your jeep alot, its not a bad idea to go around checking all your grounding wires, and giving them a good crank or two to make sure your not "wiggiling" your wires loose. Also never hurts to clean all your connections on a slow rainy day in the shop. Regular maintinence on the small stupid stuff surprisingly pays off!
