Abstract

The invention relates to a motor vehicle lighting device that includes a first module with at least one first pixelated electroluminescent light source where the first module can produce a first pixelated partial high beam (HB1) having a first resolution and a first horizontal angular amplitude; and includes a second module with a second pixelated electroluminescent light source where the second module can produce a second pixelated partial high beam (HB2) having an angular amplitude smaller than that of the first pixelated partial high beam (HB1) and a resolution greater than that of the first pixelated partial high beam (HB2); the pixelated electroluminescent light sources preferably being monolithic.
