Abstract
An indicator lamp for a motor vehicle is delimited at least on one side by a partition (22) running along the lamp over a substantial depth and comprises a light source (10), a flux concentrator and/or recuperator element (211), glazing (30), and an auxiliary reflecting area (212) able to direct, towards the glazing in the vicinity of the partition (22), an auxiliary luminous flux the average direction (x′-x′) of which is substantially inclined with respect to the principal axis of emission (x-x).The auxiliary reflecting area comprises a segment of axisymmetric paraboloid focused in the vicinity of the source, and the axis of which is oriented along the said average direction.
