The invention relates to an indicator light comprising: a light source; a rigid optical guide forming a column, comprising: an inlet optical surface delimiting the lower surface of the optical guide and through which the light of the light source enters into the optical guide; an outlet optical surface delimiting the upper surface of the optical guide and through which the light of the light source is emitted; a rectangular section over at least a major portion of length thereof, characterized in that, for at least one angular opening (a) centered at a preferred outlet direction, the light source is arranged on the side of the inlet optical surface, at the intersection between a longitudinal axis (A) of the optical guide, and the path of a reverse virtual ray corresponding to the path of a light ray emitted by the source in the reverse direction, the reverse virtual ray entering into the optical guide through the outlet optical surface by impinging in the preferred direction, being refracted by the outlet optical surface, and being reflected at least once by the side walls of the optical guide, and in that the inlet optical surface (9) of the optical guide comprises a planar surface portion which is arranged on the path of said virtual ray and perpendicular to said ray at the inlet optical surface.
