Adaptive Headlights

Swivelling lights turn with the steering; matrix lights switch off segments to avoid dazzling others. Some systems use cameras to detect oncoming vehicles. Static cornering lights switch on an extra light at low speed when turning. High beam assist is a simpler related feature: it switches between low and high beam automatically using a camera.

A control module uses steering angle, speed and camera data to move or shape the beam.

A fault often triggers a warning and the lights default to a fixed position. After replacing parts, calibration may be required.
