1972 Volkswagen VW Beetle Exterior Lights





1972 VW Beetle Exterior Lights

Exterior lights fall into two categories: Lights Independent of the ignition switch and lights which work only with the ignition switch on.

1. Lights Independent of the Ignition System

a. Park, Side, and License Plate Lights
Pulling the light switch knob out to the first stop supplies power to the front and rear park lights, front side lights, and license plate light. All park lights contain dual element bulbs. The forward element in the front park bulbs and the right-hand element in the rear park bulbs light when the switch is pulled. The front park and side lights, the rear park lights, and the license plate light are protected by fuses in the fuse box. The park and side lights remain on when the light switch is pulled all the way out.

b. Emergency Flasher System
Pulling the emergency flasher switch out causes the rear elements in the two front parking lights and the two upper bulbs in the rear fender fixtures to flash on and off continuously and simultaneously. The control knob and the green arrow indicator in the speedometer also flash to indicate the system is energized. Flashing continues as long as the switch is pulled out regardless of whether the car is parked or being driven.

2. Lights Dependent on the Ignition Switch

a. Turn Indicator Lights
With the ignition switch on, pushing the turn signal lever up causes the rear elements in the right-hand front park light and the upper bulb in the right rear fender fixture to flash on and off continuously and simultaneously. Pushing the lever down causes the left-hand lights to flash. Flashing stops when the lever is centered. A green arrow indicator in the speedometer flashes to indicate the system is energized. The turn indicator system is protected by a fuse in the fuse box.

b. Brake Lights
Depressing the brake pedal with the ignition switch on closes dual pressure switches completing circuitry to the left-hand elements of the center bulbs in the rear fender fixtures. The lights remain lighted until the pedal is released. A dash mounted warning light illuminates if either or both pressure switches fails. The warning light bulb lights when the ignition key is turned before the engine starts. The brake light circuitry is protected by a fuse in the fuse box.

c. Head Light
With the ignition switch on, pulling the light switch knob all the way out supplies power to the headlights as well as to the Park, Side and License Plate Lights. The headlights are switched from high to low beam and back by pulling back on the turn signal and headlight dimmer switch. Switching to high beam illuminates the high beam warning light in the speedometer. The headlights are protected by four fuses in the fuse box.

d. Backup Lights 
When backing the car, placing the gar shift in reverse closes the backup light switch illuminating the backup lights. The backup light circuit is protected by an inline fuse.
