Trijicon's Bright & Tough night sights are the ones that made the company's name. Each lamp is a sealed tritium vial in an aluminum cylinder, cushioned in silicone and capped with sapphire — a construction that survives slide velocity and hard use for years, which is why these have been standard-issue on so many duty pistols. The tritium glows continuously in complete darkness with no batteries and nothing to charge.

This is a three-dot set for Smith & Wesson M&P series pistols; note that it excludes the Shield and CORE models, which use different sight geometry. A straightforward, proven upgrade over factory polymer sights.
