Abstract
The invention proposes 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.
