Abstract

In a vehicle lamp (7) whose light exit opening (5) is covered by an elongate translucent light exit lens (9) which serves as a light guide for a light source (14) which is arranged at one (12) of its narrow end edges, in such a way that it guides light given off by the light source (14) in the longitudinal direction in such a fashion that a part thereof issues at the narrow end edge (20) in opposite relationship to the coupling-in side while a further part of said light is irradiated through the outside surface (10) of the light exit lens (9), to improve the light output it is provided that the light exit lens (9) is curved transversely with respect to the longitudinal direction and that its inside surface (24) has an optically effective structure (26, . . . , 26) which focuses the light issuing through the outside surface (10) in the cross-sections which are perpendicular to the longitudinal direction into a preferred angular range.
