Abstract
A light signalling device, particularly designed for motor vehicles. The device has The light rays of the source penetrate the cavity; and some of these rays are transmitted by the semi-reflecting zone, and others of these rays are reflected by the semi-reflecting zone, then by the reflector into the cavity in such a way as to generate a repetitive visual or three-dimensional effect of depth.The screen is configured and arranged in relation to the direction of emission of the light source in such a way that another part of the light rays leaves the cavity at the level of the screen without meeting the semi-reflecting zone.
