ABSTRACT:
A waterproof man overboard personal rescue light unit for use in detecting, locating, raging to, engaging, and rescuing personnel needing rescue is disclosed as having a body having a closed lower end and an upper end; a steady state light located proximate to the upper end of the body so as to emit a generally hemispherical light pattern when energized; a non-incandescent strobe light located proximate to the upper end of the body so as to emit a generally hemispherical light pattern when energized; at least one switch for electrically coupling the steady state light and the non-incandescent strobe light to a source of electrical power; a lens matable to the upper end of the body to create a waterproof enclosure defined by the body and the lens, and to permit a generally hemispherical emission pattern of light generated by the steady state light and the non-incandescent strobe light. The unit is preferably buoyant and attachable to a user by way of a tether. Depending upon applications, both light sources may be controlled by a single switch or by separate switches. In preferred form, the body houses disposable or rechargeable batteries to power the unit.
