How to Adjust Projector Headlights on a Pontiac
Your Pontiac's factory headlight housing can be replaced with a projector headlight assembly. While the factory headlights are sufficient, the aftermarket projector headlights improve headlight performance by focusing a beam of light onto the road surface, rather than relying on the reflective backing of the headlight housing to scatter the light. When you replace your headlights with projection headlights, however, you may need to adjust the headlights for optimal nighttime visibility.

Locate the adjustment screws on the backside of the headlight housing. Adjust both screws with a torx-head screwdriver until the center of the headlight beam sits at the bottom of the garage door where the door meets the ground. Adjust the headlights until both headlights overlap by about 50 percent. The exact direction you need to turn the headlight adjustment screws will depend on the original position of the headlight.
