An indicator light for a motor vehicle, the light being of the type comprising a substantially point light source (10) and a flat closure glass (20), situated in front of the source, together with beam-forming means for forming a beam of light rays (x'x) propagating along a given general emission direction of the light, said beam-forming means comprising: a generally flat or concave mirror (30) disposed behind the light source and comprising a set of stepped reflecting zones (32, 32, 33) inclined to reflect light rays from the source towards the glass; and a set of deflector zones (201, 202, 203) which are generally in the form of concentric rings on the glass, each zone being formed by a set of narrow prisms all having the same profile within each zone, said profile being designed as a function of the average direction respectively of direct rays and of reflected rays received by said zone.
