The Hydrostar Seastar S.O.S. Deluxe full-function light is the ultimate companion for any paddler or boater, offering everything you need for lighting in one compact, waterproof package. Use the flashlight setting for shore landings at night or as a 360-degree viewable white light for paddling. Switch to a red/green setting to use as an auxiliary boating light or switch to the super bright 1 watt LED strobe or S.O.S. signal for emergency use. An integrated clip allows for quick attachment to a PFD; a safety whistle is built in to the lanyard snaphook and the base of the light is magnetic to provide additional mounting options.
