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.
