It is definitely impressive that this keychain will not only light up your hand in the middle of the night in a pitch dark room, but it can also help you navigate to another location should that be necessary. Originally we developed this glow technology for the US Air Force. We have now enhanced the Super Bright Glow and this new improvement makes it an excellent low level ambient light. The photo luminescent glow is charged by any light source, and will continue to emit a glow for 24 hours with varying intensity. This extra safety feature is now available for our Keychain with Breathalyzer.
Lose your keys? Just turn off the lights and look for the glow.
