Abstract
Abstract An illuminated safety helmet including a protective core and a plurality of light emitting diodes (LEDs) disposed around the protective core. The LEDs are sequentially illuminated by control circuitry. A housing encloses the control circuitry and a power source for powering the control circuitry and the LEDs. The housing is electrically connected to the LEDs and is removably attached to the protective core of the safety helmet. An impact resistant shell or a skin of stretchable material is disposed on the external or internal surface of the protective core.
