Active main beam
Active main beam is a function which uses a
camera sensor at the top edge of the windscreen
to detect the headlamp beams from oncoming
traffic or the rear lights of vehicles in front, and
then switches from main beam to dipped beam.
The function can also take streetlights into
account.
Main beam is reactivated when the camera sen-
sor no longer sees any oncoming vehicles or
vehicles ahead.
Car with halogen headlamps
The lighting returns to main beam about a sec-
ond after the camera sensor no longer detects
the headlamp beams from oncoming traffic or the
rear lights from vehicles in front.
