Vertical aim adjustment
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
•
(1) 8 feet (2.4 meters)
•
(2) Center height of lamp to
ground
•
(3) 25 feet (7.6 meters)
•
(4) Horizontal reference line
2. Measure the height from the
center of your headlamp to the
ground and mark an 8 foot
(2.4 meter) horizontal reference line
on the vertical wall or screen at this
height (a piece of masking tape works well). The center of the lamp is
marked by a 3.0 mm circle on the headlamp lens.
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover the left-hand headlamp with an opaque cloth.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge of high
intensity light towards the right. If
this edge is not at the horizontal
reference line, the beam will need to
be adjusted.
5. Locate the vertical adjuster on
the headlamp, then turn the
adjuster either clockwise (to adjust
up) or counterclockwise (to adjust
down) aligning the upper edge of
the light pattern to the horizontal
line.
6. Move the opaque cloth to cover
the right-hand headlamp and repeat
Steps 4 and 5 for the left-hand
headlamp.
