MANUAL HEADLAMP AIMING
PROCEDURE
1. Ensure your vehicle is loaded to your
specific “travel and camping” conditions.
2. Remove all snow, ice, dirt and other debris
that may affect the ride height of the vehicle.
3. Find a flat area at least the length of your
motor home plus 7.62 meters (25 ft) with
a vertical flat surface that is at least 3.0 m
(10 ft) by 3.0 (10 ft) at one end (a driveway
and garage door could be used).
4. Measure 7.62 m (25 ft) and position the
motor home so the headlamps are 7.62 m
from the vertical flat surface and secure by
placing in park or Neutral and setting the
parking brakes.
5. Inspect your headlamp system and
determine if it is a “Type 1” or “Type
2” system. A Type 1 system has a separate
HI and LOW beam and uses four lamps. A
Type 2 system can be identified by locating
the number “2” embossed on the lens of the
lamp.
6. Measure the height from the ground to
the center of the low beam filament of the
driver’s side headlamp. Project this height
in an exact straight line to the vertical
surface 7.62 m away from the motor home.
Mark the height of the filament and center
line on the vertical surface. This will have
set up a “coordinate system” for protecting
the headlamp’s beam on the vertical surface.
7. Repeat step 5 for the passenger’s side
headlamp.
8. Activate the head lamp system. Using
Figure 1 below the projected beam on the
vertical surface is to be located as follows.
a. Type 1 Head lamps: The projected
beam should be centered vertically and
horizontally on the vertical surface as
marked in step 6 and 7.
b. Type 2 Head lamps: The top edge of the
projected beam is to even with a horizontal
line parallel to a line formed by the two
head lamp filament centers and to the right
of the vertical center line of each head lamp.
9. If the head lamps do not meet the
alignment criteria adjust the “Vertical “and/
or “Horizontal” positioning as shown on
the attached figure, rotate the knobs and/or
screws on the head lamp. When turning the
knobs and/or screws watch the direction in
which the projected beam moves to help
understand which direction on the beam
moves in relation to turning each.
10. Remember, this procedure is only a
guideline and is not a substitute for having
head lamps professionally aligned.
CAUTION
The following procedure is not a substitute for having
the head lamps professionally aligned by a certified
head lamp alignment professional to the Society of
Automobile Engineering standards. Improper head
lamp alignment may result in poor visibility during
reduced light conditions and may result in an accident.
