*When the ignition switch is ON position
*When the generator is generating electricity
*When the light control SW is OFF position
*When the parking brake SW is OFF position
2. Headlight Operation
*The headlight comes on at the LOW position when the dimmer SW is turned to the low beam position with the light control
SW being HEAD position.
*If the dimmer SW is turned to the HIGH position with the light control SW being HEAD position, the headlight comes on at
the high beam position. Moreover, the high beam indicator light appears on the combination meter.
*Regardless of the light control SW positions, the headlight comes on at the low beam position when the dimmer SW is
