Care of Headlamps
The headlamps require periodic cleaning and occasional readjustment.
To clean the headlamps, remove both headlamp
doors. Clean the lenses with alcohol inside and outside. Carefully
wipe all dust from the reflectors and, if necessary, polish
them with a soft rag dipped in a mixture of lamp black and
alcohol. In polishing reflectors, always rub from the center

straight out to the rim;
never rub in circles.
Inspect the gaskets
and replace them if
they are damaged or
do not register properly.
Replace any
bulbs that are burnt
out or that show signs
of blackening. Try the
lighting switches in
all positions to see that
all bulbs burn properly.
The headlamps are designed for prefocused bulbs, so no focusing
adjustment can be made in the lamps. On this account, only prefocused
bulbs can be used in these lamps, and no other bulbs will be
satisfactory. Because of this design, aiming is the only adjustment
required by the headlamps.
Set-Up for Aiming Lamps
Place the car on a level surface with the headlamps aimed
toward and 25 feet from a garage door or other reasonably light
colored vertical surface. Draw a horizontal line on this surface
at the level of the headlamp centers. If your state requires a
loading allowance, draw this horizontal line the required distance
below the level of the lamp centers. Sight through the
center of the rear window over the radiator cap to determine the
center point of the horizontal line and draw vertical lines through
points at the right and left of this center point directly ahead of
the center of each headlamp.
Aiming the Headlamps
The lighting switches should be turned to the "Driving"
position, which means that the lower filaments will be lighted
in both lamps. The headlamp doors must be removed and one
of the headlamps covered. The beam from the uncovered lamp
should then be centered sideways on the vertical line directly
