1. An illuminating device for a vehicle, the illuminating device comprising:
an elongated light guide that has an end face to couple light into the light guide and has a lateral surface at which the coupled-in light is adapted to be totally reflected in a coupling direction; and
an elongated reflector that is arranged so that it follows the light guide, the elongated reflector being arranged at least partially behind the light guide in a main emission direction of the illuminating device and having a reflector surface that has a greater width extension than the light guide,
wherein the light guide is designed such that the coupled-in light is coupled out at a rear-side lateral surface and/or a side lateral surface facing the elongated reflector and/or at a front lateral surface facing away from the elongated reflector,
wherein the light guide and the reflector each have a corner region, in which the light guide and the elongated reflector are each arranged in a curved manner around an acute or right or obtuse angle,
wherein the elongated reflector has a non-reflective section in its corner region at which the light coupled out from the light guide in the direction of the elongated reflector is not reflected in the main emission direction, and
wherein the non-reflective section is designed as a recess.
