that the right side of the road is illuminated as far ahead as is
practicable without causing glare on curves.
The operation of the headlights is a simple one, allowing
the motorist to use either the country (upper) or the traffic
(lower) beam as traffic and road conditions demand by the use
of a conveniently located foot switch. By pullill.g the light button
on the instrument panel to the second or last position, either
the country (upper) or traffic (lower) head lamp beams are ob-
tained alternately by operating the foot switch (Fig. 36).
When the country (upper) beams are lighted, a red pilot
bulb in the instrument cluster
will be illuminated, making it
convenient for the driver to
determine when this beam is in
use. Always use the traffic
(lower) beam when meeting.
Never pass on approaching cor with
the red light burning.

is parked.

of "Sealed Beam" headlamp units are available. One of these
types is made entirely of hard glass and the other is a composite
unit consisting of a metal reflector and a glass lens. Both are
completely interchangeable from the standpoint of electrical
connections, beam patterns and physical dimensions.
No dust or moisture can get inside the "Sealed Beam" head-
lamp unit because the reflector and lens are sealed together
permanently. This feature eliminates cleaning except for wiping
off the outside of the lens and provides proper focusing and
maximum light efficiency during the life of the car. The reflector
units in both the right- and left-hand headlamps are identical
and are so designed that they cannot be installed improperly,
nor can the electrical connections be attached in any but the
right way. This feature makes replacement of a unit extremely
simple, as follows:
