U.S. Coast Guard Embraces Electronic Distress Signals

The U.S. Coast Guard is moving away from traditional pyrotechnic flares aboard its own vessels, adopting approved Electronic Visual Distress Signaling Devices (eVDSDs) as part of a broader effort to improve marine safety.

Unlike conventional flares that burn for less than a minute, electronic distress devices use bright LED lights that flash the international SOS pattern for several hours. They produce no flame, generate no hazardous residue, and eliminate concerns over expired pyrotechnic flares that require replacement every few years.

Many Coast Guard-approved electronic distress devices, when carried with a required orange daytime distress flag, now meet federal visual distress signal requirements for most recreational boats operating on coastal waters and the Great Lakes.

Boaters should make sure any electronic distress light they purchase is Coast Guard-approved, as not all LED safety lights qualify. While electronic devices offer longer life and easier maintenance, many experienced mariners still recommend carrying multiple ways to signal for help, including a VHF marine radio and, for offshore trips, an EPIRB or Personal Locator Beacon.

The Coast Guard’s transition reflects the growing acceptance of electronic distress technology and marks an important step toward modernizing emergency signaling equipment for recreational and commercial boaters alike.
