The front fog lamps (10/5-6) are activated by pressing the button for the front fog lamps in the light switch module (LSM) (3/111). The light switch module (LSM) transmits data to the central electronic module (CEM) (4/56) to light the lamps. The central electronic module (CEM) activates the relay (2/34) and the bulbs are supplied with power via the relay.
