Dimmer Switch

The dimmer switch is a momentary contact switch that is integral to the headlamp switch. The headlamp switch is hardwired to the BCM  . When the dimmer switch is pressed up or down, the switch completes a ground circuit to the BCM  corresponding to the desired action (increase or decrease illumination brightness).
