We recommend that you purchase bulbs from a Cadillac dealer.
In any event you should use bulbs having the correct voltage and candle
power. (See wiring diagram, Fig. 28.)

The light on the instrument board for illuminating the dial of the clock
is controlled by a separate push button switch located at the top of the
ignition and lighting switch. To turn on the light pull out on the switch
button. To extinguish the light, push in.

COMMUTATORS
Do not under any condition put oil of any kind on the commutators of
the motor generator.
IGNITION AND LIGHTING SWITCH
This switch makes the necessary connections for ignition and for all
lights. In addition, the ignition switch lever controls a switch in the circuit
between the generator and the storage battery. This circuit is closed when
the ignition switch is on, thus allowing current to flow from the storage
battery to the generator and causing the armature to rotate slowly. This
facilitates the meshing of the starter gears. After the engine is started and
the generator is driven by the engine the circuit remains closed, thus allowing
current to flow from the generator to the storage battery for charging.
The .adjustment for focusing the headlamp bulbs is near the top of the
lamps and is accessible after removing the lamp door.
To make the adjustment, run the car head on towards, and at right
angles to, a high fence or building, and stop when within from fifteen to
twenty feet from it. Then throw the adjustment back and forth until the
bulb is in the proper 1 position.
If in turning the screw to the right, the rays of light appear to spread
out, it indicates that the bulb is too far back in the reflector and that it should
be brought forward. To do this, turn the adjusting screw to the left until the
proper rays are shown.
If the adjusting screw be turned to the left and the rays appear to spread

TO CLEAN THE REFLECTORS OF THE HEAD AND SIDE
LAMPS
The reflectors in these lamps are plated with pure silver. In polishing
extreme care must be used in selecting materials which will not scratch the
silver.
Powdered dry rouge and a chamois skin are recommended. If the reflectors
are tarnished, moisten the rouge with alcohol, and apply with the chamois.
Then polish with a dry chamois and rouge.
The chamois should be soft and must be kept free from dust.
use the chamois for any other purpose.
