At one point I had some aftermarket one piece lights. The adjustment screw was on the back of the light and the assembly had to be removed to adjust it.

 

I plan on getting some LED halos sometime soon.. Probably gonna be one peice. Would it be too much to ask for a couple of reviews.? So far they aren't looking too great..

 

I have the one piece headlights and they suck. I can't figure out how to adjust them up or down or if just the bulbs are junk haven't looked at it to hard yet.

I had one piece housings at one time I no longer do. My adjustments where in the back, they could be reached with a small stubby screw driver but it was not easy. The actual reflective portion of the housing is what gets adjusted not the entire housing. If yours are the same as mine were it should be a gold screw with a star washer around it.
