Abstract
A light device for motor vehicles, especially a signal lamp, comprises a carrier housing (1), covered by a translucent cover (2), and an inner chamber (3) wherein at least one light source for generating light rays is mounted, and a transparent optical part (5) with at least one output surface for the output of at least a part of light rays from the transparent optical part. The light device further comprises at least one macrotexture (8) the surface of which consists of individual surfaces designed for transmission and/or reflection of a part of light rays, the macrotexture and the transparent optical part arranged in such a way that in a view of the inner chamber (3) towards the output surface through the translucent cover from the outside of the light device, the impression of a spatial effect is produced, which is even visible with the light source being off.
