Lighting device and method for illuminating a part of the environment in front of the vehicle

A lighting module (12) generates a bundle of light beams with a source (22) of light in a first propagation direction (16) along with devices (20,24) for bundling light. A reflecting device (14) deflects the bundle of light beams for the lighting module falling on the reflecting device in the first propagation direction so that the bundle is deflected in a second (18) propagation direction.
