Pyrotechnic flares are important to have onboard, but adding an electric “flare” to the safety kit can be easier for all crewmembers to use and it never expires. The SOS Distress Light, which comes with a day signal flag flashes for 60 hours, is visible up to 10 nautical miles, is waterproof and floats. It fulfills the Coast Guard’s requirements for nighttime visual distress signals. $100, www.weems-plath.com
