•(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 of the
headlamp bulb center from 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).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
4. On the wall or screen you will
observe an area of high intensity
light. The top of the high intensity
area should touch the horizontal
reference line, if not, the beam will
need to be adjusted.
To see a clearer light pattern for
adjusting, you may want to block
the light from one headlamp while
adjusting the other.

each headlamp. Usinga4mm
wrench, turn the adjuster either
clockwise (to adjust down) or
counterclockwise (to adjust up).
The horizontal edge of the brighter
light should touch the horizontal
reference line.
