A rear indicating light for a motor vehicle comprises a light source, a bonnet in front of the light source, and an optical plate in front of the bonnet. The bonnet has means for distributing essentially uniformly the radiation it receives from the light source, over at least part of the surface of the flat optical plate, which is formed with striations to align the radiation along the optical axis. These striations are grouped in at least one discrete zone on the surface of the plate, the remainder of this surface consisting of at least one optically neutral zone, while the distributing means are adapted to distribute at least some of the radiation from the light source towards the discrete striated zones.
