Drivers side lights dim
 
I noticed this before I moved. But all of the drivers side lights are dimmer than the passenger side. The lows, drl and fog lights. What would cause this?

Check the grounds?

Is there a main ground for the drivers side? Where is it?

Just thinking out loud.. check voltage at those connectors and see what it shows.

is it all OEM headlight wiring?

Not quite. I have the p&p hids in the lows, I have a wire spliced into the ground wire at the harness connector for the 4 hi mod, my drl is wired to my fogs and I jumped the relays in the fuel box so that my fogs come on with my lows. So my fogs, drl and lows are on at the same time and stay on when I hit the hi beams

unsplice all the splicing and see what happens.. sounds like alot of stuff goin on under there :jest:

sounds like a clusterfuck. i would start by un-jumping the relays in the fuel box. not sure what a fuel box is, but i'm willing to bet it has nothing to do with your headlights.

seems like a ground issue to me. pop hood and jiggle some wires.

Or before you do anything... pull a dim bulb and check voltage and resistance from the ground pin to ground. see what that shows... might pinpoint a bad connection.

But it's all of the drivers side lights. And it was supposed to be fuze box. It's part of the 4 hi mod. Ill have to dig out my voltage tester and see what it's at
