The subject inventive arrangement produces a light guide that may be of any curved shape that produces and obtains a lighting appearance of a uniform or homogenous lit appearance at the light exit face by using a single light source and a single light-reflective coupler. The present invention is premised on a light guide system that includes a light guide; a light source; and a coupler positioned at the light source that is configured to receive generated light. The coupler is adapted to produce a collimated light beam from the light source. A stepped reflective surface is formed along a light reflecting face of the light guide by a plurality of light reflective facets and a plurality of lateral surfaces, which are configured to receive and direct collimated light towards a light-emitting exit face. In addition, a number of light reflective facets are configured to collect collimated light at the light reflecting face's middle portion in intensity amounts less than collimated light at end portions of the light reflecting face.
