Day and night weapon sights have a sight element which includes a rod-shaped light guide, and a self-luminescent capsule integrally co-located within an end of the light guide. Preferably, the light guide is formed of a rod-shaped fluorescently dyed transparent plastics material and the self-luminescent capsule includes a radioactive luminescent source (e.g., tritium).
