Automatic High Beam

It uses the front camera. It detects headlights and tail lights. It improves visibility. It usually works above a certain speed and when it is dark enough, and the driver activates it with the light switch or stalk. Street lighting in towns usually keeps it on low beam. A dirty windscreen in front of the camera reduces its performance.

The camera senses other vehicles' lights.

Reflective signs can confuse it. The driver can override it.
