The neon yellow Meridian LED Strobe Light from Princeton Tec is an emergency strobe and locator light that's visible from over a mile away. The light's body is designed to be low-profile and easily attachable to a personal floating device, SCUBA tank, or other item with 1" webbing. Users can toggle between a white emergency strobe light or red locator beacon depending on their location and environment. Built to withstand the rigors of diving, the light is waterproof up to 100m.
