AUTOMOTIVE LIGHTING DEVICE

An automotive lighting device includes a low beam light source, adapted for emitting a low beam and a signlight beam, a diaphragm element and a main optical element. The main optical element includes a first zone and a second zone. The first zone is suitable for receiving a part of the low beam which has not been reflected by the diaphragm element and projecting a low beam pattern and the second zone is suitable for receiving a part of the signlight beam which has not been reflected by the diaphragm element and projecting a signlight pattern. At least part of the second zone of the main optical element is treated to provide light diffusion.
