Dual Beam

When the Headlight Switch is moved to "HEAD", battery voltage is applied to the Headlight Dimmer Switch. When the Headlight Dimmer Switch is placed in "LO", battery voltage is applied, through the closed contacts of the Headlight Dimmer Switch, to the LO Beam Lamps. When the Headlight 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 operate.
