Abstract: A lighted helmet having a protective shell having: an outside surface, a plurality of lamps which emit light from the outside surface; a power supply, typically a battery; and a motion detecting switch in communication with the power supply and the plurality of lamps. When the helmet is worn by a user, even small movements of the head produce forces, which in turn, trigger the motion detecting switch. Upon triggering of the motion detecting switch, the lamps are illuminated for a predetermined period of time. Upon expiration of the time period, subsequent motion will retrigger the switch, once again activating the lamps. The process continues until the helmet is placed in a stationary position, at which time the lamps are extinguished upon expiration of the then active time period.
