Where are the headlight grounds?

[Colleen]

I have a 2003 TJ with one headlight dimmer than the other. I had to get my rear defrost fixed as my daytime running lights were causing my rear defrost and reverse lights to not work.

Any suggestions as to where the grounds are for my headlights? It’s the drivers side. Thanks!

Odds are it's just a dirty / corroded plug or ground connection at the headlight itself. Unplug the wiring plug attached to the rear of the headlight and then reseat it which will likely cure it. If that doesn't do it, find the black wire from the headlight plug attached to a screw going into the body. That is the ground wire. Loosen the screw that holds it to the tub, clean, and then retighten it.
