EXTERIOR LIGHTS
(Continued from previous page)
Hazard
Lights
(For SE Models Only)
With the Hazard Switches in the HAZARD
position, voltage for all lights is supplied
through the Hazard Flasher. The Stop-Turn
Lights will flash repeatedly. With the Brake
depressed, the Hazard Lights will not flash.
(For GT Models Only)
With the switches in the HAZARD position,
voltage is supplied to the Turn Lights through
the Hazard Flasher. The Turn Lights flash
repeatedly. The Brake Lights remain off.
Front Marker Lights
The Front Marker Lights receive voltage
from either the Front Park Lights or the Front
Turn Lights.
With the Park Lights on, battery voltage is
supplied through the BRN wires to both Front
Marker Lights. The path to ground for the
marker bulb is through the Turn Lights. The
small Marker Light bulbs light up, but not the
larger turn bulbs.
When the Turn Lights are on, but not the
Park Lights, battery voltage is applied through
the LT BLU wires to the Marker Lights. They
glow since they are grounded through the entire
Park Lights System. As before, the small
marker bulbs light up, but not all park bulbs.
If both the Park Lights and either the LH or
RH Turn Lights are on at the same time, the
marker bulb for that side will not light up. With
battery voltage on both sides of a bulb, it will not
glow. With the Turn Lights off, however, the
marker bulb on that side will light since it is now
grounded through the Turn Lights.
License, Tail and Rear Marker
Voltage is applied through the TAIL Fuse to
the Light Switch at all times. With the Light
Switch in PARK or HEAD, voltage is applied to
all of the lights in this circuit.
(For GT Models Only)
For the Rear Pontiac Emblem Lights, with
the Ignition Switch in RUN voltage is applied
through the Fan E Fuse to the Rear Pontiac
Emblem Lights. The lights will remain on as
long as the Ignition Switch is in the RUN posi-
tion, displaying the Pontiac Emblem.
High Level Stop Light
Voltage is applied at all times from the Stop
HAZ Fuse to the Brake Switch. When the brake
pedal is depressed, the High Level Stop Light
comes on.
