Source summary
Find an alternative to tritium-based illumination used on sight scales so they remain readable at night without the radioactive material's procurement restrictions. The source requests compatibility with existing equipment, durability under field conditions and continuous illumination with minimal maintenance. This is an abridged materials-substitution request; no weapon-use instructions are included.
