This self illuminating safety device has been specially designed for marking equipment and personal property that you may need to find in the event of an emergency at night. The GlowRing Safety Marker is made from unbreakable, clear but vibrantly tinted polycarbonate encasing a Gaseous Tritium Light Source (GTLS) which does not require batteries or charging by sunlight. Water resistant to 30m and visible from 30ft in complete darkness the Nite Glowring will glow continuously for around 10 years.

Inside each GlowRing’s polycarbonate case is a 3mm diameter laser sealed glass tube called a Gaseous Tritium Light Source (GTLS.) The inside of this tube is coated with phosphor. The electrons in the gaseous tritium excite the phosphor causing it to glow continuously without any external power source.

This highly specialised technology is used in advanced military hardware or pioneering safety equipment where a guaranteed light source is needed in hazardous environments and conditions.
