Visual Procedure

1. Prepare vehicle. Refer to "Aim Preparation".
2. Park the vehicle square with the screen and with the headlamps directly over the reference line.
3. Make sure all components are in place if other work has been done on the vehicle.
4. Line up the centerline of the vehicle with the centerline of the aiming screen. This can be done by marking the vertical center of the vehicle and front windows with tape. Use these lines as "sights" to line up the centerline of the vehicle and screen.
5. Adjust the vertical tapes on the screen to match the vertical centerline of each lamp. (Measure the distance from the centerline of the vehicle to the centerline of a low beam lamp.)
6. Adjust the horizontal tapes on the screen to match the horizontal centerline of the low beam headlamp. (Measure the height from floor to the center of a low beam.)
7. Turn on the low beam lamps. Adjust the headlamps so that:
a. The left edge of the high intensity zone on the screen for the low beams is on the vertical line for each side.
b. The top edge of the high intensity zone on the screen for the low beam is on the horizontal line for each side.
