The illuminator device includes a fiber optic cable having two ends and adapted for mounting on the safety helmet so as to illuminate an exterior of the safety helmet. The illuminator device includes a light source coupled to a light interface, the light interface connected to one end of the fiber optic cable, the light source being activateable. A motion detector detects motion or motion of a preselected type or amount and provides a signal to activate the light source upon detection of motion or the preselected motion.
