FIELD: transport lighting engineering. SUBSTANCE: lighting system has two light sources. Each source is mounted in focal points of doubled ellipse-shaped concentrators of light flux of light sources, diffusers made in form of condenser lenses, and light guide system. Input ends of the light guides are mounted at the second focal points of ellipse-shaped concentrators, and output edges - at focal plane of condenser lenses. Each concentrator interacts with light guides which have output edges to correspond to the same mode of light distribution (lower beam or upper beam). EFFECT: improved efficiency. 3 dwg
