The Hi-Viz LiteWave H3 Tritium/Litepipe Night Sights MPSN621 is a handgun night sights set designed for low-light and daytime sight alignment.

This model uses tritium illumination and LitePipe fiber technology to maintain visibility in both bright and dark environments. The front sight features a green tritium insert with an orange ring, while the rear sight is orange for enhanced contrast. It is designed to fit Smith & Wesson M&P Shield pistols in 9mm, .40 S&W, and .45 calibers with factory sight height compatibility. The sight set installs into standard slide dovetail cuts and uses a fixed front and rear configuration.

In practical use, the LiteWave H3 system provides continuous illumination supported by a 12 year tritium warranty for routine range and carry applications.
