LNK-AL15 Survivor Locator Light is a reserve battery-powered emergency light to be installed on single or multiple flotation devices in order to indicate the location of survivors in water caused by aviation accidents. When the flotation device enters the water, the survivor locator light will automatically activate upon contact with or immersion in seawater or freshwater. It emits a continuous steady white light with a light intensity greater than 1cd for at least 8 hours, clearly indicating the position of the floating device and improving the success rate of rescuing survivors.
