In a vehicle lamp, in particular a side marking lamp for a motor vehicle, comprising at least one light source and at least one optical system () arranged in the beam path of the light source, the substantially conical light beam issuing from the light source impinges directly on the optical system () and shines therethrough, wherein the optical system () is such that it produces therefrom a cruciform light distribution ().

Vehicle light having a cruciform light distribution

A lamp, in particular a motor vehicle lamp, comprises a light distribution device (') into which the light of at least one light source () is fed in such a way as to produce a light flux which is firstly propagated through the light distribution device substantially parallel to a light exit surface defined thereby. Components are deflected out of the light flux by means of coupling-out structures (&#x2032;) for delivery through the light exit surface. To achieve good illumination of the light-transmitting surface the coupling-out structures are a plurality of coupling-out layers which are arranged at spacings in succession in the direction of propagation of the light flux and which comprise a medium whose optical refractive index is different from that of the medium filling the intermediate spaces between said layers, wherein the coupling-out layers are so inclined relative to the propagation direction of the light flux at a predetermined angle that its main component passes through them without a substantial change in direction while a minor part is reflected towards the light exit surface.
