HEADLAMP CONTROL SYSTEMS
Two headlamp controls usually are provided: one to turn them on and off and the other to select
between the upper and the depressed beams.
The control switch is usually a master-type switch controlling the head, tail, parking, and instrument
One type of headlight switch is a push-pull type that mounts on the instrument panel. When the
switch is pulled out, it will have two "ON" positions. The first ON position will turn on the
taillights and parking lights. Pulling the switch out to the second ON position will turn on the
headlights in addition to the lights turned on at the first ON position. This type of switch also has
a built-in control rheostat that controls the intensity of the instrument lamps. The rheostat is
controlled by turning the knob.
