Lincoln Corsair: Maintenance / Adjusting the Headlamps

Vertical Aim Adjustment

The assembly plant properly aims the headlamps on your vehicle. If your vehicle has been in an accident, have the alignment of your headlamps checked by your authorized dealer.

1. 8 ft (2.4 m).
2. Center height of lamp to ground.
3. 25 ft (7.6 m).
4. Horizontal reference line.

1. Park the vehicle directly in front of a wall or screen on a level surface, approximately 25 ft (7.6 m) away.
2. Measure the height of the headlamp passing beam optical center from the ground and mark an 8 ft (2.4 m) horizontal reference line on the vertical wall or screen at this height.

   Note: To see a clearer light pattern for adjusting, block the light from one headlamp while adjusting the other.

3.  Switch on the low beam headlamps to light the wall or screen and open the hood.

   

4. On the wall or screen, observe a flat zone of high intensity light at the top of the right-hand portion of the beam pattern. If the top edge of the high intensity light zone is not at the horizontal reference line, adjust the headlamp.

   

5. Locate the vertical adjuster on each headlamp. Turn the adjuster either clockwise or counterclockwise to aim the headlamp.
6. Close the hood and switch off the lamps.

Horizontal Aim Adjustment

Your vehicle does not require horizontal aim as it is non-adjustable.
