Abstract
A motor vehicle lighting device that includes a means for emitting a first cut-off light beam along an optical axis where the cut-off is a substantially horizontal line that includes a cut where the cut extends in a coordinate system formed by a horizontal reference axis (HR) that is parallel to a first horizontal axis (HI) passing through the substantially horizontal line; and a vertical reference axis (VR) that is perpendicular to the horizontal reference axis (HR) and to an optical axis; where the optical axis passes through the coordinate system's center; Also is included a means for emitting a second light beam that is horizontally divided into a multitude of selectively activated light segments where the light segments illuminate a zone located astride of the first horizontal axis (HI) that is characterized by the cut, which includes a proximal longitudinal end along the horizontal reference axis (HR) between 1.25° and 1.5° or between −1.25° and −1.5° and which includes a lower vertical end along the vertical reference axis (VR) at a height of −0.75° or below.
