Figure 2-60.- Blackout light/ headlight switch.
With no lights on, the main switch can be turned to the left without operating the
mechanical switch to get blackout marker lights (including blackout taillights and
stoplights) and blackout driving lights. But for stoplights for daylight driving or
headlights for ordinary night driving, you must first lift the mechanical switch lever
and then turn the main switch to the right. The auxiliary switch gives panel lights when
the main switch is in any of its ON positions. But it will give parking lights only when
the main switch is in service drive (to the extreme right). When the main switch is off,
the auxiliary switch should not be moved from the OFF position.
DIMMER SWITCH
The dimmer switch controls the high and low headlamp beam function and is normally
mounted on the floorboard (fig. 2-61) or steering column (fig.
2-62). When the operator activates the dimmer switch, it changes the electrical
connection to the headlights.
