GENERAL DESCRIPTION
.
The lighting system includes: the main lighting switch,
stop light, dimmer, and backing lamp switches, head-
lamps, parking lamps, stop, tail and directional lamps,
instrument illumination and indicator lamps, and the
necessary wiring to complete the various circuits. A
fuse panel provides convenient power take offs and fuse
clips for the appropriate circuits (fig. 1).
Chevrolet and Chevelle headlamp installation is all
new in that the headlamps are located in the radiator
support with adjusting screws and springs. Eliminating
the need for having separate headlamp housings. Chev-
rolet and Chevelle headlamp retainers and springs are
interchangeable.
Chevy n headlamp housings are new because of revised
front end styling and Corvette front end lighting is basi-
cally carryover.
Front fender lamps have been added as an option for
Chevrolet models and as standard equipment on Caprice
series.
Camaro models use single headlamps and the Rally
Sport model headlamps are covered by a retractable
section of the grille when lamps are not used. The sec-
tion of the grille covering the headlamps folds back when
lights are required; the headlamps are stationary. The
covering is retracted by a small electric motor mounted
to the headlamp housing. The headlamps are automat-
ically uncovered when the headlight switch is pulled "ON"
for illumination. If at any time the electrical circuit
becomes inoperative, the lamps can be uncovered manu-
ally. The ignition switch must be
"ON"
in order to close
the headlamp doors.
Parking lamp for Chevelle and Chevrolet models are
new due to revised front end sheet metal and bumper
styling. Parking lamps are located in the bumper on
Chevrolet, Chevelle and Chevy n models
Camaro parking lamps are located in the radiator
grille except for the Rally Sport models on which the
parking lamps are in the valance panel. For styling
reasons, the lens is white and an amber glass bulb is
used. All Camaro parking lamps require a separate
ground wire to assure a good ground contact because of
the plastic grille and painted contact surfaces.
The Chevrolet tail, stop, and directional lamps are in
one housing with a three section lens design on Impala
and Caprice sedans. The center lens for Impala series
is the back-up lamp. The center lens on the Caprice is
a tail lamp with the back-up lamps being located in the
rear bumper. Chevrolet station wagons have three indi-
vidual housings with three lenses, the center lamp being
the back-up. Biscayne and Bel-Air sedans have a single
housing and lens for tail, stop, and directional lamp with
a similarly constructed back-up lamp inboard and adja-
cent to it.
Chevelle tail, stop, and directional lamps are a single
lens design that follows through with the rear fender
styling. The back-up lamp is located in r.ear bumper.
Camaro models except Rally Sport have tail lamps
with integral back-up lamps mounted inboard of the rear
fenders between the trunk opening and bumper. The
Rally Sport model has dual tail lamps in the rear housing
and valance mounted back-up lamps.
Corvette, Chevy n, and Corvair tail and directional
signal lights are carryover. The Corvette has new back-
up lamps center mounted above the license plate opening.
