An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.
