LIGHTING SWITCH (COMBINATION
SWITCH)
The lighting switch has OFF, PARKING and HEAD­
LIGHT positions. The Parking position is used to light
up the front side marker light, parking light, taillight,

the headlight position, the headlight, in addition
to all
the lights mentioned above, is turned on through the
lighting relay.
