Glow in the dark shotgun beads?

[jaholder1971]

I'm looking for a tritium shotgun bead for use on my HD shotgun, I've got a HiViz fiberoptic bead on there now but it needs more light than I've got in the house at night to work.

I'm not looking for ghost ring or anything, just a simple tritium bead.

They're about $30.
