Abstract

A double headlamp adaptive lighting device for motor-vehicles, comprises a first headlamp (3) to generate a predetermined basic light beam and a second headlamp (4) having a pair of microlens matrices (11, 12) movable relative to each other so as to be able to select a plurality of different additional beams which are added to the basic beam to generate different total beams.
