Abstract
This invention concerns an automatic control device, particularly for the switching of car headlights from full to normal beam. The control device comprises a light commutator-detector for exploring the space in front and on at least a surface of the motor vehicle to generate, in response, electric signals, an amplifier-comparator circuit controlled by the signals in arrival from the commutator-detector and suitable for generating threshold signals, to a commutation circuit controlled by the threshold signals of the amplifier-comparator circuit to control the switching between full beam and dipped beam of the headlights.
