Inspired by markers used in the military for friend or foe identification, the Pharos Marker is a webbing-compatible, glow-in-the-dark marking device. Easily attach the Pharos Marker to pack straps, PALS webbing or any other webbing up to 1 inch wide for easy identification of your gear in the dark.
Our custom built glow tube is filled with the most advanced glow-in-the-dark compound available. Optimized for maximum brightness and longevity, this compound will lose only 5% of its ability to glow after 10 years. The 3 mm x 22.5 mm chamber is also compatible with common tritium vials available on the market, which glow continuously for at least 10 years.
The GITD tubes can be replaced with 3 mm x 22.5 mm tritium vials from http://www.mixglo.com
