3. Remove retainer by rotating counter-clock-wise, allow-
ing the Sealed Beam unit to be removed.
4. Remove the reflector plug from the unit as shown in
Figure 29.

HEADLAMP AIMING
Place the car on a level surface with a light colored
vertical screen 25 feet ahead of headlamp lens.
NOTE: The setting of headlamps should be accomplished
with the car empty; that is without driver or passengers
and with a minimum amount of gasoline in the gas tank
.
FIGURE 30
Draw a horizontal line on this surface at the level of a
point 3" below the headlamp center, as shown in Figure 30.
This line is 29-3/4" above the floor line. If, however, your
state requires a loading allowance, draw this horizontal line
below the above line by whatever amount that is required
in your state.
Locate center of car by sighting through the center of the
rear window along the right and then along left of wind-
shield center bar and mark these two points on the horizon-
tal line. The point midway between these two lines is the
center of the car which should be temporarily located on the
screen.
Draw vertical lines (B-B) and (C-C), on the screen to the
right-and left of the center line at a distance equal to one-
half of the center to center distance (28-1/2") between the
two lamps.
Place dimmer switch in position which produces highway
(upper) beam on screen.
Remove headlamp lens rim.
Move the light beam to the right or left by turning the
horizontal adjustment screw (C), Figure 30. Raise or lower
the beam by turning the vertical adjustment screw (A).
Cover one lamp to obscure the beam of light and then
adjust the beam from the other lamp so that the center of the
zone of highest intensity falls on the intersection of the
horizontal line A-A, Figure 30, 3" below the headlamp
center, and the vertical line directly ahead of the lamp.
Repeat the operation for the other lamp. No further
adjustment is needed for the traffic (lower) beam.

DIMMER SWITCH
The headlamp be am is controlled by a foot operated
dimmer switch mounted in the floor panel. Dimmer
switches have two single terminals and a double terminal,
Figure 31. The single terminals connect to the battery and
the he ad la m p lower (dim) beam. The double terminal
connects to the headlamp upper beam (bright) and to the
beam indicator lamp on the instrument panel.
DIMMER SWITCH CHECK:
1. Disconnect all wires from the dimmer switch.
2. With the light switch on, connect the dimmer switch
battery wire to a test lamp and ground the other lamp
terminal, Figure 32.
