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.

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.
