Aligning depo headlights
Just installed a set of depo headlights and need held on aiming the lights at the right height. If I pull the car infront of a wall how far away from the wall should the car be? Also how high should the beam of light be from the ground? Any advice helps. Thanks

I adjusted mine by driving it. They have a sharp enough cut-off that you can see where it's at when you drive. Just aim them so that the lows cut off before they get in peoples eyes, but they're still high enough that they shine far.

you should be about 20' from the wall....measure from the ground to the center of the lamps and the beam on the wall should be slighty lower than the measurement you took

I just painted (black) and installed my DEPO lights with 6000K HID's two weekends ago. As others have said they only adjust up and down and it's best to adjust them all the way down. The low beam and high beam move together, it's not a separate adjustment, did you paint your lights and install HID's?

Does anyone else agree with the post above mine that they should be adjusted all the way down?
I also am installing mine with HIDs soon

Park 20' away from a wall....measure from the ground to the center of the depo projector...say it's 24". now go to the wall and put a horizontal line on the wall at 22". This is so your lights aren't going to blind someone a ways down the road. Now all you have to do is adjust the lights until they hit that line on the wall.

If you need to adjust them after they are installed, remove the plasctic piece that sits parallel to the ground and is right in front of the front wheels. You should be able to reach your arm up there enough to get to the adjustment scew.

I can't take credit for this but here is the proper procedure for the factory lights:
There is one error in the explanation above. The Torx screws adjust both the high and low beams as the beams are contained in one unit. The two screws are there to provide separate adjustments for vertical and horizontal directions of the light. Here are the instructions from the GM Service Manual.
