Lighting device active portable or placed on a bicycle.

The device (1) active lighting of a vehicle comprises a first optical (has) with a first light source (16) for long distance illumination, which is controlled by a control unit (2), and a second optic (d) with a second light source (17) for short-distance illumination, which is controlled by the control unit. It comprises a light sensor (3) to determine the light intensity of a place where the vehicle and permit the controller to adjust the intensity of the control light of the light sources, if enabled and if the intensity of ambient light is below a predetermined light threshold. In addition, there is a speed sensor (4a, 4b) for determining vehicle speed when used on a path, for that the control unit controls the activation of the first light source from at least one predetermined speed threshold. It is also provided an orientation sensor (5a, 5b, 5c) for orienting the light sources depending on a curve fitting the vehicle in use.
