Bodies of water are secured with warning signals, life preservers or buoys. All these items are useless, however, when visibility is poor or at night. Life light is a combination of a buoy, a life preserver and a warning signal that is illuminated thanks to an LED water battery. In an emergency, the device can be located immediately, even at night.
