Abstract: A lighting and/or signaling module for an automobile vehicle, the module comprising a light source e, a reflecting surface and a toroidal lens. The reflecting surface is calculated in such a manner that the rays coming from the module, reflected then transmitted by the lens, are perpendicular to and encounter a circular arc A. This geometry of the outgoing rays endows them with a toroidal wavefront which allows the principle of constancy and of reversibility of the light path (Fermat's principle) to be applied and, consequently, a straightforward calculation of the reflecting surface. The beam thus produced can notably provide a daytime running light or, alternatively, a direction indicator function. The module may comprise another lighting function of the high-beam type using another portion of the lens.
