The Universal Glow Marker (UGM) Patch is a powerful tool for gear identification in total darkness—no batteries, bulbs, or electricity required. Originally developed to meet U.S. Navy specifications for submarine emergency markers, these rugged, reusable glow bars are now trusted for everyday and survival use alike.

Each UGM is crafted from high-quality glow-in-the-dark epoxy resin, delivering up to 24 hours of afterglow with a quick charge from any light source. Lightweight yet tough, it can be mounted with the included hook backing or easily drilled for keychain or lanyard carry. Whether you’re tagging gear, prepping a go-bag, or adding visibility to a doorknob in a pitch-black hotel room, the UGM gets the job done—sterile, bright, and clean.
