An illumination device for single-track motor vehicles that emits bundled light in the form of a light beam bundle, that in a first propagation direction (A) is aimed at the roadway area located in front of the motor vehicle. The illumination device (SCH) comprises a light module (LIM) that emits light in a second propagation direction (B) and where at least one optical reflection device (SPI) is arranged in the beam path of the light. Light emitted by the light module (LIM), first of all, will hit the optical reflection device (SPI) and then will be deflected by the latter into the first propagation direction (A). At least one optical reflection device (SPI) can be swung around at least one swing axis. According to the invention, at least one swing axis (SA1) lies essentially in a plane that extends parallel to the longitudinal vehicle midplane (FLE) or that is the longitudinal vehicle midplane (FLE).
