BMW Develops Dynamic Brake Light System

This additional brake light function, which is still limited to the EU / ECE area, warns following traffic in two stages when the motorcycle in front brakes hard or makes an emergency braking maneuver. Stage one is activated when the motorcycle decelerates from speeds above 50 km/h. In this case the brake light flashes with a frequency of 5 Hz. As the motorcycle approaches standstill (< 14 km/h), the hazard warning flashers are also turned on in the second stage. These remain turned on until the motorcycle accelerates again to a minimum speed of 20 km/h.
