ACR SM-3 SOLAS Lifebuoy Marker Light

The ACR SM-3 SOLAS Lifebuoy Marker Light is a compact, high-intensity safety device designed for commercial and recreational vessels operating in open water. Built by ACR Electronics—a trusted name in marine emergency equipment—this marker light mounts directly to standard lifebuoys and serves as a critical visibility aid during man-overboard situations or emergency rescues.

The light activates automatically upon water immersion, requiring no manual intervention—a critical feature when seconds count in a rescue scenario. Its robust, weather-sealed design ensures reliable operation in harsh saltwater environments, while its compact profile of 3 x 3 x 11 inches makes it easy to install without affecting lifebuoy handling.

Serious boaters and commercial operators choose the ACR SM-3 because it delivers non-negotiable reliability where human lives depend on visibility. Install one on every lifebuoy aboard your vessel to exceed USCG and SOLAS requirements, ensuring your crew and passengers remain visible to rescue personnel, even in low-light conditions.
