This emergency strobe light can be a real life-saver. It's a G.I.-type strobe that will flash 60 times per minute with at least a one-mile visibility (up to three in clear conditions). It's made of tough ABS plastic, so the strobe can handle years of abuse. The Coast Guard-approved strobe attaches to various mounts with either of the included options: an industrial safety-pin style clip or a strong magnet.
