ABSTRACT:
The lighting and/or signaling system according to the invention comprises at least one lighting and/or signaling device which is able to emit at least one light beam and is equipped with at least one actuator for adjusting an angle of the light beam, and at least one actuator control device for controlling the actuator. According to the invention, the actuator control device transmits an active setpoint information item to the actuator only when a current value of the setpoint information item differs substantially from a previous value of the setpoint information item. The improved actuator control incorporated in the system according to the invention helps to achieve greater reliability and a longer service life.
