FORD 2005 F-550 v.1 - Manual (Page 45)

2. Measure the height from the
center of your headlamp (indicated
by a 3.0 mm circle on the lens) 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).
3. Turn on the low beam headlamps
to illuminate the wall or screen and
open the hood. Cover one of the
headlamps so no light hits the wall.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam will need to be adjusted so the edge
is at the same height as the horizontal reference line.
5. Locate the vertical adjuster on
each headlamp, then use a E5 Torx
socket to turn the adjuster either
counterclockwise (to adjust down)
or clockwise (to adjust up) aligning
the upper edge of the light pattern
up to the horizontal line.
6. Repeat step 3–5 for the other
headlamp.
7. Close the hood and turn off the
lamps.
