Tritium-capable ending beads?

[jacobconroy75]

All,
I've been hunting around the web for hours tonight. Has anyone ever seen an ending bead that can accept tritium tubes? I'd like something in Ti, maybe gold-anodized, not too big around, and hopefully something that can be purchased without waiting/hunting for a year.

I know...tall order it seems. Thought I'd ask around.

I stole this off the Interwebs:

I have not, but could you modify a tiny flashlight, I have a pelican 1810 on my keychain that might work with modifications.
