2010 FORD SUPER DUTY light

•(4) Horizontal reference line
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 from that lamp 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 Steps 3–5 for the other
headlamp.
7. Close the hood and turn off the
lamps.

BULB REPLACEMENT
Lamp assembly condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, drip marks or droplets)
•Fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp water
leak) are:
•Water puddle inside the lamp
•Large water droplets, drip marks or streaks present on the interior of
the lens
Take your vehicle to dealer for service if any of the above conditions of
unacceptable moisture are present.
