Exterior lighting

The lighting functions are integrated into the footwell module (FRM).

These lighting functions are:

• Side lights
• Main-beam headlights
• Headlight flasher
• Turn signals
• Hazard warning lights
• Brake lights
• Dipped headlights
• Reversing light
• Front foglights
• Rear foglight
• Parking lights

Besides the lighting functions, other exterior lighting functions are also integrated in the footwell module:

• Light monitoring
• Headlight range adjustment
• Emergency operating mode if the footwell module should fail
• Lamp replacement

  (important lighting functions are substituted by other lights being actuated in the event of individual lights failing.)

• Follow-me-home lights
• Visual alarm after anti-theft alarm has been triggered

  (the visual alarm is given as per encoding with hazard warning lights, turn signals with dipped headlights or turn signals with main-beam headlights.)

• Actuation of bi-xenon headlamps

All lighting functions except the additional brake light are supplied with a pulse-modulated signal by the footwell module (FRM). This PWM signal allows constant brightness of exterior lighting.
