Ambient Light Sensor

Range: Light/Dark
The BCM uses this input in order to determine whether the ambient light level is light or dark. The BCM uses this information in the operation of the ALC and the DRL features.

When the BCM considers the ambient light to be light, LIGHT is displayed. When the BCM considers the ambient light to be dark, DARK is displayed.
