So both headlights on my YJ refused to come on tonight when I went to go to work. They used to act up a little bit, like one would be dim or something, but I could just jiggle the harness around and it would be fine. I jiggled everything around, but they wouldn't come on. The marker lights came on fine. Is this a bad relay or switch or something? I appreciate any help.

I would first check the headlight and dimmer switch mounted in the vehicle. This is a common bad component

There are grounds on the backside of the grill for the headlights, clean those up. Check your fuses too, under dash and under hood.

fyi dimmer switches are $10 cheaper at the dealer than autozone. If that ends up being your problem.
