Tail Ring 2.0
Tail Ring 2.0
These tail rings sit unobtrusively around the tail-switch-boot on almost any flashlight, adding a little extra style, and making them easy to spot in the dark. They fit most lights, using the standard 14 or 16mm tail-boots. Installation couldn’t be easier, just press-and-go. New version 2.0 brings better fit & finish, new colors, and even brighter glow! (most of our colors will last at least all night on a single charge)
These are powered using strontium aluminate,* the brightest and longest lasting glow technology. Performance varies dramatically by color, however green is the brightest and longest lasting. Charging is best done with a bright light source. We recommend UV lights (320-400nm), the common 365nm LED lights are great. Learn more about colors and our glow tech.
Installation is quick, easy, and completely reversible. Simply center the tail ring on the boot, and press down firmly. If necessary, gently pull back the rubber working your way around the perimeter. Removal is equally as quick and easy, simply reverse the process pulling up gently on the tail ring, pulling back on the rubber boot working around the perimeter if necessary.
