Cornering Lights
Adaptive front head lamp systems use cornering lights to increase the horizontal area that is illuminated by vehicle headlights when turning a corner. There are static cornering lights and dynamic cornering lights. Static cornering lights employ additional light sources or additional reflectors in the head lamp to direct light to the vehicle's turning direction.

With dynamic cornering lights, the entire head lamp component swivels horizontally when the car goes around a corner. The speed and angle of swiveling is determined by an electronic control unit that gathers information from the vehicle speed sensor, steering wheel position sensor, and yaw rate sensor.
