the hand control in the second position and select the
"city" beam with the foot switch.
Two types of lighting are available in the driving compartment—the
dials of all instruments are lighted from the
edges, while direct light for the ignition switch and for reading
maps is provided by the lock lamp.
The two-position switch for these lamps is mounted on
the instrument board flange just below the center panel. In
the left-hand position, the instrument lamps are lighted,
but only if the headlamps are also turned on. In the righthand
position, the instrument lamps and lock lamp are
lighted, regardless of the headlamps.
The headlamps are controlled by two switches: a three
position button at the left of the instrument panel and a foot
switch below the clutch pedal. The beam in use at any time
shows up in illuminated letters on the indicator.
The three
headlight beams

When driving on unlighted straight roads, set the hand
control in the third position. Select the "driving" beam
with the foot switch, but change to "passing" whenever a
car from the opposite direction approaches within 500 feet.
When driving on unlighted winding roads, set the
hand control in the second position, and use the foot switch
to select the "driving" beam and to switch to the "city"
beam whenever another car approaches. The "city" beam
is the only safe passing beam for winding roads. (See drawing
below.)
Courtesy and safety both demand the use of the pass*
ing beams exactly as outlined. We urge every Cadillac
