DESCRIPTION AND OPERATION
HEADLIGHTS
Four sealed-beam headlights are
used. The two outboard lights have
two filaments each for low beam and
high beam, and arc marked by a
numeral "2" molded in the glass lens.
Locating tabs molded in the glass
allow the mounting of the No. 2
lights in the outboard headlight sup-
port frames only. The low beams are
used for city driving, when meeting
oncoming traffic on the highway, and
for No. 2 headlight alignment.
The inboard headlights with a
numeral "1" molded in the glass lens
have only one filament and are used
for highway driving along with the
high beams of the No.
2
headlights.
Locating tabs molded in the glass
allow the mounting of the No. 1
lights in the inboard headlight sup-
port frames only. A conventional
beam selector switch is located on the
floor board near the left.
Quick disconnect terminals are
provided ai the left and right of the
radiator support assembly. The termi-
nals are color coded. Like colored
terminals are connected together.
The green wire with a black stripe
supplies current to the headlight high

IN-CAR ADJUSTMENTS AND REPAIRS
HEADLIGHT ALIGNMENT
All headlight adjustments should
be made with a half-full fuel tank
plus or minus one gallon, with a
person seated in the driver's seat.
the car unloaded and the trunk
empty except for the spare tire and
jacking equipment, aTtd recommend-
ed pressura in all tires. Before each
adjustment, bounce the car by push-
ing on the center of both the front
and rear bumpers, to level the car.
To align the No. 1 headlights (in-
board lights) by means of
a
wall
screen, select a level portion of the
shop floor. Lay out the floor and wall
as shown in Fig. 2.
Establish the headlight horizontal
centerline by substracting 20 inches
from the actual measured height of
the headlight lens center from the
floor and adding this dimension ( di-
mension "B," upper diagram Fig. 3)
to the 20-inch reference line ob-
tained by sighting over the uprights.
Draw a horizontal line two inches
below, and parallel to, the head-
light horizontal centerline. Then draw
the headlight vertical centerlines on
the screen as measured on the car
(dimension ''A," upper diagram Fig.
3).

stripe supplies the low beam fila-
ments. The black wire with a yellow
stripe supplies the parking lights
(Fig. 1 ).
HORNS
The Lincoln is equipped with a
pair of tuned horns controlled by a
relay. The horn button closes the
relay contacts, completing the circuit
to the horns. One of the horns has a
high-pitched tone; the other has a
low-pitched tone. The horn circuit
is shown in Figure 1.
mension ·'B" for the No. 2 lights is
the same as ''B" for the No. l lights,
dimension "A" is as measured on the
car. Note that the line of adjust-
ment of the No. 2 lights is the
horizontal centerline of the No.
2
lights. Turn the headlights to low
beam and adjust each No. 2 light
as shown in Fig. 3.
Each headlight is adjusted by
means of two screws located under
the headlight trim ring as shown in
Fig. 4. Always bring each beam into
final position by turning the adjusting
screws clockwise so that the head-
lights will be held against the tension
springs when the operation is com-
pleted.
Some states may not approve of
the 2-inch dimension for the No. 1
headlights. Check the applicable
state law, as a 3-inch dimension
may be required.

it in position, making sure that the
locating tabs are placed in the posi-
tioning slots.
