When driving on the motorway, the motorway beam provides improved roadway illumination – without dazzling oncoming traffic or vehicles driving ahead.
The motorway beam utilises the large quantity of light and optimised lateral and forward illumination provided by xenon plus headlights. A vehicle electronics component continually analyses the vehicle speed via sensors. After a brief interval of travelling above 110 km/h, the system determines this to be a motorway drive and automatically switches from the dipped beam mode to the motorway mode. By specially positioning the shield in the xenon plus headlights, additional light can be focused by an aluminium reflector and projected far in advance of the vehicle, but without dazzling any other drivers. This extends visibility more than twofold: from 70 m in the dipped beam mode to 150 m in the motorway beam mode. Thanks to this increased visibility, at a speed of 130 km/h, two additional seconds are gained in which to react to objects or occurrences ahead of the vehicle. Consequently, the motorway beam considerably increases driving safety.
