Abstract
An indicating light or side lamp display for a motor vehicle comprises a substantially point light source, a flux recuperator such as a mirror, for reflecting the light from the source towards the outside in the form of an essentially parallel beam, and, interposed in the path of the beam, an intermediate screen and a cover lens. The intermediate screen has a set of optical cells, each of which includes on an internal face a substantially spherical surface for spreading the light, and, on an outer face of the screen, a set of at least two flat facets which are oblique with respect to the plane of the intermediate screen.
