The Nite Glowring, manufactured by a company who produce “military equipment and other need-to-see-at-night items”, will provide you with a glowing light using tritium – the same kind of radioactive material that was used for this other glowing keychain.
This tiny keychain glows continuously for 10 years using tritium, a radioactive material used in watches, compasses, gun sights and other products you might use in a dark environment.
