All lights except my headlights and front parking lights work on my 78 CJ5. The side parking lights are pretty dim. I see on my harness that there are three wires going into the headlight. I'm assuming one is low beam power, one is high beam power, and one is ground. Is the headlight frame supposed to be grounded for them to com on?
