The adaptive brake light improves the active safety as it provides a better signalling effect during emergency stops.

In the event of emergency braking from a speed of 50 km/h and upwards, all brake lamps start flashing. This provides a warning to all traffic behind the vehicle and helps shorten the drivers' reaction time. If the vehicle is braked from a speed of 70 km/h and upwards to a complete standstill, the hazard warning lamps switch on automatically.
