Headlamp Switch: Description and Operation
HEADLAMPS
Voltage is supplied to the Light Switch at all times. The Light Switch includes a Self-Resetting Circuit Breaker. The Circuit Breaker opens when
the Headlamp circuit draws too much current. When the Circuit Breaker opens, it interrupts the current flow. With no current flow, the Circuit
Breaker cools off and resets automatically. When the Light Switch is in HEAD, the Headlamp Dimmer Switch directs voltage to either the Low
Beams or High Beams. The High Beam Indicator also receives voltage along with the High Beams.
