How do you adjust projectors??
 

So i have projector headlights now. How do i go about adjusting them? There are two screws on each light but not to sure if they actually adjust anything.

Get on level ground with a solid wall that has some sort of lining available like a brick wall or against a garage. Those 2 screws adjust left and right, and up and down. Bring a peice of wood to make sure they are EACH aligned correctly. You can block off one at a time, then down the center to compare.
