Automatic high-beam headlight switch-off when oncoming traffic is detected

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

The light cone of the high-beam headlights has a range of about 400 m. The detection range of the image sensor has a range of up to 1000 m. This ensures that the image sensor detects oncoming vehicles before their drivers can be dazzled by the light cone of the high-beam headlights. If the image sensor detects an approaching vehicle, the high-beam assistant control unit sends a switch-off recommendation to the front electronic module (FEM). The FEM switches off the high-beam headlights.
