2015 bmw 535
The BMW Dynamic Brake Force Display helps drivers behind your car know how hard you are braking in order to help them react quickly and reduce the risk of a rear end collision. Each of the brake lights are split into two different sections, one that is used during normal braking, and a second that only lights up when heavy braking is detected to increase the brake lights’ intensity. Just before the vehicle comes to a complete stop the hazard lights are also activated. When the vehicle accelerates again the hazard lights are automatically deactivated.
