HEADLIGHT AND FOG LIGHT
GENERAL DESCRIPTION
The circuit consists of the headlight, fog light, lighting switch, dimmer·passing switch, fog light switc~, high­
beam indicator,
lighting relay, tail relay and fog light relay. When the lighting switch is turned on by s~tting it
at the headlight position, the lighting relay is activated to turn on the headlight. The optical axis oft he hE ad light
can be turned up or down by operating the dimmer switch while the head light is on.
The passing switch is independent
of the lighting switch, and the optical axis ofthe passing light can bE turned
up only while the switch lever is pulled up and held in this state.
When the fog
light switch is turned on while the headlight on at low-beam, the fog light relay is acti ated to
turn on the fog light.
