On the wall or screen you will 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, the headlamp needs to
be adjusted. 5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the horizontal
reference line.
6. Close the hood and turn off the lamps.
