The Cyalume SOS survival signal light features a lightstick with an attached cord that, when activated, produces a highly visible 360-degree circle of light. By spinning its handle, it creates a continuous light ring visible up to 1 mile (1.6 km) on land or sea level and up to 3 miles (4.8 km) from the air. This makes it an effective and practical signaling device for emergency situations, enhancing your chances of being located quickly by rescuers.
