A headlight includes a system for illumination of dual parking lights on a motor vehicle using a single light source positioned in front of a headlight reflector. The reflector has one surface section that reflects light to an optical waveguide in the front, and around the circular edge, of the reflector that serves as the parking light of the headlight, and another surface section that reflects light to a planar mirror reflector located in front of the light source and reflector, at an inclined angle to the main beam's optical axis. An optical waveguide element is attached to the reflector's surface extending behind the reflector in a direction opposite to that of the main beam direction. The planar mirror reflector focuses received light to a focal point at the entrance of the optical waveguide element, which couples the light to a neighboring optical waveguide associated with a neighboring headlight.
