Introducing the ACR SM3 Marker Light — a compact, high‑intensity LED beacon designed to mark a crew‑overboard site with unstoppable visibility when every second counts.

• 360° visibility with a bright LED strobe that reaches about 2 miles, ensuring the MOB marker is seen from all directions.
• Self‑righting, water‑activated operation — the SM‑3 automatically rights itself and activates when it hits the water, so you don't have to worry about activation in an emergency.
• Durable, UV‑resistant construction in a polycarbonate case that stands up to harsh marine environments.
• Floats upright in all conditions, keeping the light visible even if the device shifts.
• Lightweight and compact with easy bracket installation. The included bracket maintains the same hole pattern as SM‑2 for simple retrofit with no adapter plate required.
• Long‑life power runs on 2 AA Energizer L91 Lithium batteries (not included); user‑replaceable to extend life beyond disposable lights.
• Extended operating life delivers 40+ hours at 30°C (86°F) or 24+ hours at -1°C (30°F), ensuring reliable signaling during long events or voyages.
• USCG/MED/SOLAS approved for worldwide use, helping vessels meet lifebuoy self‑igniting lighting requirements.
• Rugged testing drop‑tested to 76 meters, giving confidence across platforms and vessel sizes.

Whether you’re outfitting commercial vessels, offshore platforms, cruisers, or any application requiring a dependable Crew Overboard Marker light, the SM3 provides a rugged, maintenance‑friendly solution that shines when you need it most. Its replaceable lithium power source and self‑igniting design reduce downtime and simplify compliance, while the compact form factor and retrofit‑ready bracket make upgrading fast and easy.
