Headlamp range adjustment is controlled by the light switch module (LSM) (3/111) which is directly connected to the actuator motors.

If the thumb wheel in the lamp switch module is turned, information about the position of the wheel is transmitted to the actuator motors. The actuator motors change the angle of the reflectors in the headlamps. The headlamp range can be adjusted in 16 stages.
