The Firefly Kit Marker is a rugged, self-powered glow tag designed to help users identify gear, equipment, or locations in complete darkness—without the need for torches, batteries, or chemical light sticks. Each marker is fitted with a 2 x 12 mm trigalight® GTLS (Gaseous Tritium Light Source) sealed in a durable clear polycarbonate body. Visible from up to 25 metres away in total darkness, it’s ideal for tagging bags, control panels, safety equipment, or tactical kits. A corrosion-resistant wire screw-clip allows for secure, fast, and flexible attachment to both fixed and portable items. Key Features: Self-illuminated tritium light – glows for 10+ years No batteries, charging, or ambient light needed Visible up to 25 metres in darkness Wire screw-clip for quick and secure fixing Available in 9 glow colours for ID or function marking Rugged, impact-resistant clear polycarbonate housing Performs reliably in all climates – even underwater Safe, sealed GTLS technology – zero external radiation Suggested Uses: Marking tools, cases, or survival kits Gear identification in low-light or tactical operations Route or asset marking in camping, hiking, or emergency use General-purpose night visibility without electricity How It Works: Each Kit Marker contains a sealed borosilicate glass capsule filled with tritium gas. As the gas decays, it emits low-energy beta particles, which excite a phosphor coating inside the tube, causing it to glow continuously—no moving parts, no switches, and no maintenance.
