Fog/Driving Lamp Indicator: Description and Operation
Rear Fog Lamp Indicator - Description
DESCRIPTION
A rear fog lamp indicator is standard equipment on all instrument clusters for certain markets where rear fog lamps are available. However, on vehicles
not equipped with the optional rear fog lamps, this indicator is electronically disabled. This indicator is located above the fuel gauge and to the left of
speedometer on the cluster overlay.
The rear fog lamp indicator consists of a stencil-like cutout of the International Control and Display Symbol icon for Rear Fog Light in the opaque layer
of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. An
amber Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the indicator to appear in amber through the translucent
outer layer of the overlay when it is illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit board.
When the exterior lighting is turned ON, the illumination intensity of the rear fog lamp indicator is dimmable, which is adjusted along with the cluster
general illumination lighting using the panel lamps dimmer control sleeve on the left multi-function switch control stalk.
The rear fog lamp indicator is serviced as a unit with the instrument cluster.
