Abstract
A light device, especially a signal lamp for motor vehicles, comprising a carrier bushing (1) with a translucent cover (2) and an inner chamber (3), wherein a lighting unit (4) is mounted providing the light signaling function, and one light source (91), and a filter (6) with at least one first input surface (83) for entry of at least part of light rays (100) generated by the light sources, and with at least one first output surface (82) designed to emit first light beam (102). The filter includes first segment (8) with the first output surface and second segment (7) with at least one second input surface (73) for entry of at least part of light rays generated by the light sources, and with at least one second output surface (72). The shape of the second output surfaces creates a designer element as a light emitting pattern emitted from those surfaces.
