Visual Aiming Preparation Procedure
Important:
Some state and local laws specify requirements for headlamp aim. Comply with all of these laws when performing any
headlamp aiming operations.
Headlamp aim should be checked:
• When a new headlamp capsule is installed.
• If service or repairs to the front end area have, or may have, disturbed the headlamps or their mounting.
The aiming screen should meet the following criteria:
•
The area will consist of a level surface large enough to allow for a vehicle and an additional 7.62 m (25 ft) measured from face of
lamps to the front of the aiming screen.
• The screen will be 1.52 m (5 ft) high x 3.66 m (12 ft) wide with a matte white surface well shaded from extraneous light, and
properly adjusted to the floor on which the vehicle stands. Provisions should be made to align the aiming screen parallel with the
vehicle.
• The screen shall be provided with a fixed vertical centerline, two laterally adjustable vertical tapes, and one vertically adjustable
horizontal tape.
• If a regular commercial aiming screen is not available, the screen may consist of a vertical wall having a clear uninterrupted area
approximately 1.83 m (6 ft) high and 3.66 m (12 ft) wide. The surface should be finished with a washable non-gloss white paint.
•
After the aiming screen has been set up in a permanent location, paint a reference line on the floor directly under the lens of the
lamps to indicate the proper location of the headlamps when they are being aimed:
- Distance between headlamps (1)
- Center line of screen (2)
- Adjustable vertical pointer (3)
- Adjustable horizontal tape (4)
- Diagram of light screen (5)
- Vertical center line ahead of right headlamp pointer position (6)
- 7.62 m (25 ft) (7)
- Car axis (8)
- Adjustable vertical pointer
- Horizontal center line of lamps
- Vertical center line ahead of left headlamp
Prior to aiming the headlamps, the following steps must be taken:
Remove any snow, ice or mud from the vehicle.
