Abstract
A lighting device for a motor vehicle, including a first lighting module adapted to project a pixelized first beam with a first resolution and a second lighting module adapted to project a pixelized low beam type second beam with a second resolution lower than the first resolution, the first and second lighting modules being such that the first and second beams overlap vertically at least in part to form a global beam, the device including a control unit able to control selectively a plurality of pixels of the first and second beams so as to project a motif in the global beam, characterized in that the control unit is adapted to control at least one pixel of each of the first and second beams when the motor vehicle enters a turn so as to create a movement of the motif in the global beam.
