Headlight aiming:
4.) The vehicle’s fuel tank must be completely filled.
5.) Bounce the vehicle several times to normalize the suspension.
6.) To simulate actual driving conditions, someone should be seated in the driver’s seat .
7.) Locate the vertical aim adjusting screw. This adjustment must be made before the horizontal adjustment.
8.) Look at the beam angle gauge for vertical movement on top of the headlight assembly. The bubble on the gauge should not deviate from the center of the gauge. If adjustment is required, turn the vertical aim adjusting screw.
9.) Look at the beam angle gauge for horizontal movement. The center mark (red line on the inner scale) should not deviate from the black line on the outer case. If adjustment is required, turn the adjustment screw at the rear of the beam angle gauge.
10.) Recheck the vertical beam angle gauge. If the headlamp has moved and further adjustment is required, turn the vertical aim adjusting screw.
11.) Recheck the horizontal beam adjustment and adjust if necessary.
12.) Sometimes it’s better to buy new headlights than to try to make old headlights work. Or if the headlighs are taking water in or are cracked it’s better to purchase new headlights.
