Aiming Headlamps (Visual Aim)

LOCATION




^ Darken an area large enough to allow for the vehicle and an additional 7.62 m (25 ft) measured from the face of the headlamps to the front of the screen.
^ Verify that the following items are level:
- The bottom of the screen
- The floor that the vehicle rests on
Compensate for an unlevel floor.

AIMING SCREEN
1. Use an aiming screen that meets the following specifications:
^ A height of 1.52 (5 ft)
^ A width of 3.66 m (12 ft) (3)
^ A matte white surface
^ Shaded from ambient light
^ Properly adjusted to the floor that the vehicle rests on.
^ Moveable in order to allow parallel alignment with the rear axle of the vehicle.
^ Positioned in order to allow a horizontal line to pass an equal distance midway between the two headlamps.
2. Ensure that the screen is equipped with the following items:
^ A vertical centerline (5)
^ Two laterally adjustable vertical pieces of tape (2)
^ One vertically adjustable horizontal piece of tape (6)
3. If a standard commercial aiming screen is unavailable, use a wall that meets the following specifications:
^ A clear uninterrupted area at least 1.83 m (6 ft) high by 3.66 m (12 ft) wide
^ A surface finished with a washable, no-gloss white paint
4. After setting up and locating the aiming screen, paint or tape a reference line on the floor. The reference line should be 7.62 m (25 ft) from the screen.
5. Park the vehicle with the front of the headlamps directly over the reference line.

VISUAL PROCEDURE




1. Prepare the vehicle. Refer to Heed/amp Aiming (Preparation).
2. Park the vehicle according to the following specifications:
^ Square with the screen
^ With the headlamps directly over the reference line
3. Verify that all components are in place if other service has been performation the vehicle.
4. Perform the following steps in order to line up the center line of the vehicle with the center line of the aiming screen:
4.1 Use tape in order to mark the vertical center of the vehicle and the front windows.
4.2 Use the tape lines as sights in order to line up the centerline of the vehicle and the screen.
5. Adjust the vertical tapes (1) on the screen in order to match the vertical centerline of each lamp.
Measure the distance from the centerline of the vehicle to the centerline of the low beam lamp.
6. Adjust the horizontal tapes on the screen in order to match the horizontal centerline (3) of the low beam headlamp.
Measure the height from the floor to the center of a low beam.
7. Turn ON the low beam lamps.




8. Adjust the headlamps according to the following conditions:
^ The left edge of the high intensity zone on the screen for the low beams is on the vertical line for each side.
^ The top edge of the high intensity zone on the screen for the low beams is on the horizontal line for each side.
^ Adjust the high beams so the beam is directly in the center of the high intensity zone where the horizontal and vertical lines meet.
