so i put after market head lights in the jeep and i was wondering if there is a way to adjust the brightness of the lights cause the driver headlight side is a lot bitter then the passenger side headlight

 

You might have a bad ground.

 

Let's see if this makes sense,

I had the same problem with my aftermarket headlights, except they were both too dim. If I understand right, Pepboys told me that it was the socket behind the headlight unit that was bad. It is a cheap fix but it might be worth a try.
