Sirius Signal says its new battery-operated SOS Distress Light is the only Coast Guard-compliant alternative to pyrotechnic flares.

The device uses an LED with a visibility of 10 miles, doesn’t expire and is submersible, buoyant and lightweight. It meets Coast Guard requirements for night visual distress signals

(46 CFR 161.013) and meets all federal requirements when combined with the included daytime distress signal flag. Sirius Signal, San Diego, (888) 526-0005. siriussignal.com
