Screen Methods

First locate the vehicle so that it is square with the screen and with the front of the headlamps, directly over a reference line which has been painted on the floor.

Locate the center line on the aiming screen so that it is in line with the center of the vehicle. This can be done by sighting through the center of the rear window of the vehicle. Mark the center of the front and rear windows with narrow strips of masking tape. Move the vehicle until it is in alignment with these 2 points. Use these "sights" to locate the centerline of the aiming screen, directly in line with the vehicle's axis.
