Abstract
A signal light for vehicles has first and second light sources emitting first and second light beams. An optical waveguide contains an entry section with a light entry surface for the light beams. A focusing surface focuses the light from the light sources in a direction (L) in which the light is guided. A deflection section contains a deflecting surface where all of the light is deflected at a deflection angle. In a waveguide section, the light undergoes total internal reflection at an outer surface of the waveguide section, guiding it in the light guidance direction (L) to a light emission surface on the waveguide section. The light sources are placed such that the beams strike the same light entry surface. The light beams are diffused in relation to one another at a diffusion angle difference (Δφ), and the different diffusions of the beams cancel each other out.
