Thanks for the tritium links... that's very helpful. We'll see what we can do... anybody know the 23x3mm vials... that seems a pretty large surface... how easily can those break if something sharp would it the surface of such a vial (if being recessed in a grove)?
I think if the vial was nestled in a groove and covered with clear
epoxy resin it would be almost impossible to break it.
