Saw Beavis had the Glow version.
had some Ideas for you -
Add Tritium Vials. They are inexpensive and easy enough to work with. Proper adhesive is the 'Norland Optical Adhesive #61'- Use a UV Light to Optically cure it.
Titanium versions <- EDIT - So there is a titanium line I found out.
Just some ideas for you.
