Orion Personnel Marker Light (PML)

The Orion Personnel Marker Light (PML) is a compact, wearable illumination device designed for marine safety and emergency visibility. This USCG-approved light attaches securely to clothing or life vests, providing a bright green light output that remains visible for up to 8 hours of continuous operation. The device meets federal maritime safety standards and is widely used by rescue personnel, offshore workers, and mariners who require reliable location marking in low-light or no-light conditions.

The extended 8-hour runtime makes the PML practical for extended operations, emergency protocols, and situations where battery replacement is not immediately possible. The bright green wavelength (approximately 510–520 nm) is optimized for human eye sensitivity and atmospheric transmission, cutting through fog, spray, and darkness more effectively than other visible colors. At just 0.15 lbs, the light adds negligible weight to a life vest or survival kit. The rugged construction packaged in a heavy-duty blister card ensures the unit withstands marine environments, including saltwater exposure and rough handling typical of commercial and recreational marine applications.

This marker light is essential for anyone operating on or near open water where search and rescue visibility is critical. Coast Guard-approved equipment carries regulatory weight in commercial maritime operations and is required gear on many commercial vessels and fishing platforms. The simple clip attachment accommodates standard life vest loops, harnesses, and clothing webbing without modification. For recreational boaters, offshore anglers, rescue teams, and maritime professionals, the Orion PML provides dependable emergency visibility at an economical price point.

Personnel marker lights represent a proven, low-cost solution to man-overboard and emergency location scenarios. The Orion brand is recognized within maritime safety circles for producing compliant, field-tested equipment. Whether required by regulation or chosen as a personal safety redundancy, the PML addresses a specific, high-consequence use case where failure is not an option.
