The water activated/manual unit is a state-of-the-art rescue light that uses a microprocessor to combine all the recommended features of a rescue light into one product. When you hit the water, the light will automatically turn on into a strobing mode to attract rescue. When rescue is close, you press the switch and it goes into a steady light to direct rescue towards you. After rescue, you press the switch one more time to turn it off. The light will reset back to water-activated mode.
Each unit has 2 LED lights that burn at up to 28 candela each, over 35 times as bright as required by the U.S. Coast Guard
In steady light mode, the lights burn for 24 hours on one set of batteries, 3 times longer than required by the U.S. Coast Guard
In strobing mode, the lights burn for 27 hours on one set of batteries, over 3 times longer than required by the U.S. Coast Guard
For use with 2 each AA Alkaline or AA Lithium Batteries
