T w o adjusting screws on each headlamp pro-
vide for accurate aiming of the headlamp beam
on a l l 37 series cars except the 37-90. O n a l l V - 8
and V-12 cars the position of thc-headlamp beam
may be moved to the right or to the left b y turning
the side adjustment screw located inside the
radiator shell. T h e beam m a y be raised or
lowered by turning an adjustment screw located
in a depression i n the bottom of the lamp body.
The horizontal adjustment of series 37-90 lamps
depends o n the correct - mounting of the lamps.
The vertical adjustment is similar to the other
37 series cars, the reflector being tilted b y means
of a scerw in the bottom of the lamp body.
The headlamp beams are to be aimed w i t h the
lens and door in place i n order to avoid the possi-
bility of adjustment being changed when the
door is reinstalled. M o s t accurate aiming c a n
be secured w i t h headlamp testing equipment.
Several types of equipment now available c o m -
mercially will do a most satisfactory j o b .
If testing equipment is n o t available the lights
can be aimed using a screen drawn u p according
to the dimensions given i n the illustration i n

as follows:
1. Place the car o n a level floor 25 feet from
the screen.

W h e n replacing the headlamp bulbs there is a
possibility that the adjustment m a y be changed.
Therefore, when a new b u l b is installed, the head--
lamp adjustment should be checked after the door
has been reinstalled.
