Fog Lamps

The fog lamp switch is integrated into the headlamp switch. When the fog lamp switch is engaged, the SJB provides ground for the fog lamp relay coil (integrated into the SJB), which then energizes and routes voltage to the fog lamps. The fog lamps can be turned on when the ignition is in run or accessory, the parking lamps are on, and the high beam headlamps are off.

On vehicles equipped with HID headlamps, the fog lamps are used for the Daytime Running Lamps (DRL), if this feature is enabled.
