DESCRIPTION





The headlamp switch (2) (also known as the Rotary Light Switch/RLS or light switch module) is located in the left outboard air outlet bezel (3) on the instrument panel just outboard of the instrument cluster bezel. This switch is the primary driver control for the exterior lighting systems. Only the switch bezel and rotary knob are visible on the outer surface of the air outlet bezel. The black plastic switch bezel is labeled at each detent position with either white text or an International Control and Display Symbol icon, which clearly identify its many functions. The switch knob is marked with the International Control and Display Symbol icon for Master Lighting Switch.

The black, molded plastic switch housing and bezel encloses the switch rotary knob mechanism and the light switch circuitry including the switch contacts. The switch circuitry includes integral internal backlighting elements, which illuminate the switch markings for visibility when the exterior lighting is turned ON as well as Light Emitting Diode (LED) units to indicate the switching status of certain exterior lighting features. A connector receptacle is integral to the back of the switch housing. Two molded plastic mounting features integral to the switch housing are used to secure the switch within a receptacle integral to the back side of the air outlet bezel with two screws. The switch is connected to the vehicle electrical system through a dedicated take out and connector of the vehicle wire harness.

Several versions of the headlamp switch are available, which vary with the optional exterior lighting features on the vehicle. The headlamp switch cannot be adjusted or repaired and, if ineffective or damaged, the entire switch unit must be replaced.
