Abstract: Lighting device for a vehicle moving without an engine and on wheels, such as bicycle and tricycle, comprising two lights supplied from a generator (1) comprising a stator and a rotor drivable by a vehicle wheel through projecting members (34) cooperating with the spokes (34) from said wheel, said generator (1) comprising at least sixteen heteropolar poles (27) distributed over 360.degree. facing an induction winding formed by a single coil (26) also extending over 360.degree., said poles (27) and coil (26) being movably mounted relative to one another, and the stator being so fastened to a vehicle fork (23) that the generator (1) be co-axial with the axis (21) of that wheel driving the rotor.
