High Beam, Auxiliary Main Beam, Headlight Flasher

The control motor for high beam activation is hard wired to the vehicle
electrical system control unit (light master). The headlight control unit is
not responsible for activating the high beam headlight in the headlight
module variants.
The auxiliary main beam headlight is also activated by the vehicle elec-
trical system control unit (light master) and its output cannot be
regulated. The vehicle electrical system control unit (light master)
activates the headlight flasher functions. The required bulbs and motors
are activated directly for this purpose.
• Only the auxiliary main beam is activated when terminal 15 is "ON"
and terminal 56b (dipped beam) is "OFF".
• The auxiliary main beam and the main beam magnet is activated when
terminal 15 is "ON" and terminal 56b (dipped beam) is "ON".
• There is no headlight flasher function when terminal 15 is "OFF".

Cornering Light

We differentiate between the variants Static cornering light and Dynamic
cornering light for the cornering light function. The driver's visible area is
larger and this contributes further to improving active safety. The road is
illuminated even better because the two light beams lie side-by-side and
do not focus their light on one point. The headlight control unit has the
relevant software for calculating the required parameters.

Static Cornering Light

The purpose of the static cornering light is to light up the adjacent area
in front of and beside the vehicle with a large beam spread and homoge-
neous linking with the rays of light emerging from the main headlight.
The headlight control unit calculates the required value for the static cor-
nering light bulb from the input values received via the CAN bus.
