did you check your fuses it might have blown its near the battery

Alignment is a possibility.

Usually it's wiring.... 20yo OEM 18ga wiring.

I rewired mine to run off the batt/alt and ran all new 10ga wire with new clips for the bulbs and my headlights are bright as day.

Ya switch the bulbs around for sure. It could be the bulb is mis-marked.

Allighnment is another good one because that will make 1 look more bright than the other one. I am guessing you have one that is noticeabley brighter than the other.

And just plain old crappy wire. Voltmeter time. Check the amperage running into and out of both sets of wires.

Fuse??? I think both of the lights would be out if a fuse was blown but that's just an opinion.

Did you touch the glass of the bulb during install?? If you did it could be trying to go out prematurely if you are running hallogens.

I will do some checking, but to add,.... when I turn on to high beam the one that is really low almost goes off completely.

Well that says : a lose ground wire or a short. That's not the bulb.
