Abstract
A lighting or signaling device for a motor vehicle which is capable of emitting a linear beam in the direction of an optical axis and which comprises a point light source that emits light rays radially around a source; a light ray guiding plate; wherein the light guiding plate is shaped so that the light rays generally propagate in incident propagation planes normal to the plate between the light source and the reflection edge and in reflected propagation planes normal to the plate between the reflection edge and the output edge.
