Headlamp: Description and Operation

When the Headlamp Switch is moved to "HEAD," battery voltage is applied to the Headlamp Dimmer Switch. When the Headlamp Dimmer Switch is placed in "LO," battery voltage is applied, through the closed contacts of the Headlamp Dimmer Switch, to the LO Beam Lamps. When the Headlamp Dimmer Switch is placed in "HI," battery voltage is applied to the HI Beam Lamps and HI Beam Indicator. The LO Beam Lamps, HI Beam Lamps and HI Beam Indicator are permanently grounded so that when battery voltage is applied, the lamps turn "ON."
