Abstract: A safety-related signalling device for a motor vehicle including a light guide, a first light source capable of emitting a light beam that illuminates a lateral face of the light guide to allow the light beam to propagate in the light guide, and a reflective screen having a front face located at a distance and across from a rear face of the light guide. The light guide is translucent and light-coloured, and the reflective screen promotes diffuse reflection of the light from the light guide so as to homogenize and intensify, on a front face, the light emitted by the light guide.

Abstract: The invention relates to a process for manufacturing a shell, comprising a decorative film, implementing a first step of molding a plastic material so as to form a first element. The invention is characterized in that the manufacturing process implements a second step that consists in applying a decorative film against a front face of the first element, then a third step of overmolding a plastic material over at least one portion of the decorative film and of the first element so as to hold the detective film between the first element and a second element of the shell.

Abstract: The invention relates to a lighting device for a signal light of a motor vehicle, generating increased light propagation in a light guide. To this end, the lighting device comprises a light guide defined by a front face, a light source illuminating a first end of the light guide, and a first mask which is positioned in front of the light source and a part of the front face of the light guide, such that the first mask hides the light source from an observer looking at the front face of the light guide. Advantageously, the front face of the light guide, facing the first mask, is at least partially covered by a separating layer reflecting the light emitted by the light source.

Abstract: Optical device (2A, 2B, 2C) for a motor vehicle providing two separate lighting functions, comprising an optical housing (4) open at a front face (12). The optical housing (4) comprises a first light source (18) arranged for illuminating a first surface (32). The optical housing (4) also comprises a second light source (20) arranged for illuminating a second surface (40), the second surface (40) being a concave shape and arranged for reflecting a light beam (34B) emitted by the second light source (20) in the direction of the front face (12) of the optical housing (4). The invention is wherein the first surface (32) is positioned between the front face (12) and the second surface (40) and in that the first surface comprises a channel (42) through which at least a portion of the light beam (34B).
