Abstract: A smart lighting system for a vehicle is described. The smart lighting system includes at least one signal generator, and a lighting stem assembly. The lighting stem assembly further includes a signal receiver; a light control PCB module, and at least one light source. The at least one light source may be a rotatable lighting source, and the left indicator light and the right indictor light. Upon receiving signal by the signal receiver from a signal generator, the light control PCB module controls the operation of the rotatable lighting source, and the left indicator light and the right indictor light. The signal generator may generate the signal based on detection of gesture by a motion sensor mounted on a helmet of a rider.
