Abstract

The present invention relates to an indicator light, particularly for an automobile, comprising a catadioptric element such that its position in the light and the preferred orientation of certain of its catadioptric prisms allow a zone adjacent the zone normally imposed by the geometry of the light to be illuminated. The invention is more particularly applied to the corner lights of automobiles.
