NEW Firefly Tinted Green Kit Marker

The Firefly Tinted Kit Marker is a compact, self-illuminating tag designed to mark equipment or locations in low-light or total darkness—without the need for flashlights or chemical glow sticks. Each marker features a 2 x 12 mm trigalight® GTLS (Gaseous Tritium Light Source) housed within a clear, impact-resistant polycarbonate enclosure.

Visible up to 25 metres in total darkness, the Kit Marker is ideal for marking tools, survival kits, control panels, or assets in tactical, emergency, or camping environments. A corrosion-resistant wire screw-clip makes it quick and easy to attach to both portable and fixed equipment.

Key Features:

• Self-powered glow – no batteries, switches, or charging required
• Continuous illumination for 10+ years
• Visible up to 25 metres in darkness
• Wire screw-clip for secure and flexible attachment
• Robust, clear polycarbonate housing – lightweight and durable
• Functions in all environmental conditions, including underwater
• Cold, silent, and maintenance-free light source

How It Works:

Each Kit Marker contains a sealed borosilicate glass vial filled with tritium gas. As the gas naturally decays, it emits low-energy beta particles that excite a phosphor coating on the inner surface of the vial—producing a constant, soft glow. Safe, non-electrical, and certified non-emissive, these tritium light sources operate reliably in all environments for over a decade without any upkeep.
