Turn Signal Light, Hazard Warning Light,
and Stoplight

General Description

The circuit consists of the starter switch, turn signal light
(front and rear), turn signal light switch, hazard warning
light, flasher unit, stoplight and stoplight switch.
When turning on the respective switches with the starter
switch on, the turn signal light will operate. When the
turn signal light is flashing, the indicator light in the meter
also starts flashing. When the hazard warning switch is
turned on, the current flows to the flasher unit through
the hazard warning switch to cause the hazard warning
light to flash, independent of the position of the starter
switch. At the same time, the indicator lights in the meter
also start flashing.
The stoplight switch will turn on and the light comes on
once the brake pedal is depressed, independent of the
position of the starter switch.
