I found a set of bosch euro lights in the junkyard, and I finally installed them on my car, but one is so dim it barely works, and the other side works fine.

I checked several times that the wires are put in the new plugs in the right order, and I am sure that part is right. There is 12v at the pins in the plug where it attaches to the light, and 11.4v where the plug attaches to the bulb. Any ideas what could be wrong?

I am terrible with electrical problems, I know someone else could probably fix it in 5 minutes but I will most likely end up just taking them off and putting them in a box someplace and looking for another set of headlights later.
