Abstract
The present invention proposes a lighting device for a motor vehicle comprising a first module that projects a first pixelated high beam, a second module that projects a second pixelated writing beam onto the road, and a third module that projects a third low beam cut-off. The first, second and third modules are arranged such that the first and second beams overlap at least partially vertically; and the second and third beams overlap at least partially vertically.
