Don't you have the "Level" bubble on the top of your headlight assembly? Park the car on a level surface and turn the geared adjustment screw to center the bubble, thats the vertical adjustment. Aim them horizontally with the screws on the inboard tops of the assembly, so they point about 10 degrees to the right of the car. Then park the car pointed at a white wall and see if the lights look right to you when you're sitting in the driver's seat. Other than that you can go find a shop that has an optical aimer and let them do it. Mike
