Abstract

The signal light (1) for a road vehicle is integrated with a headlight (18). The lamp for the headlight (20) is in the center and is surrounded by a reflector (19). An elongated light conductor (3) surrounds the reflector and may be bent into a C-shape which is open at the top. It has individual light sources behind its light outlet surface and is surrounded by the headlight housing (2).
