Abstract

The invention relates to a vehicle lighting unit with an optical conductor system, having a light source and means for concentrating the beams of this source onto the entrance end of a transparent rod, the rod extending along a longitudinal axis A and having obliquely relative to the longitudinal axis a plurality of reflecting facets at which light emerges at a specific intensity, the facets cooperating with optical lenses which are arranged at the exit of an optical conductor in the path of the elementary light bundles reflected by the facets.According to the invention, it is provided that light-controlling elements are present which permit the deflection or passage of light by changing thereflection at the facet.
