High-beam assistant on the BMW 5 Series Sedan.

The high-beam assistant is an optional feature in the BMW 5 Series Sedan that automatically switches the headlights from high beam to low beam as soon as it detects oncoming traffic or adequate street lighting. A camera integrated in the rear-view mirror monitors ambient brightness and traffic conditions, and can detect approaching traffic up to one kilometre away. When the road ahead is clear again, the system automatically switches up to high beam again.
