Recently got a couple of glowing tritium keychains. My wife thought it was silly that I would order a couple of $14 keychains, but when she saw them in the dark she immediatly confiscated one. Said it would be good for finding he keys in her dark purse.

Anyway, I just wanted one to play with. Couldn't leave well enough alone so I chucked it up in the drill press and turned it down to a bit over a 1/4" diameter, shortened it, re-polished it and drilled a new hole for the split ring. Much smaller now. The new and improved version is on the lanyard for my bed side flashlight. No feeling around in the dark for it now. Glowring is bright and easy to find. I'd highly recommend one on any emergency flashlight. After all, you usually need your flashlight when it's dark.

BTW, the green are the brightest and the easiest color for your eyes to register.
