The Meprolight Hyper-Bright Fixed Night Sight Set (brand part number 402243121) equips a Glock 17, 17L, 19, or 22 with fixed day-and-night sights built around Swiss-made green tritium vials. Meprolight surrounds the front vial with a bright fluorescent yellow outline ring for fast acquisition in daylight, while the rear sight carries a black outline to keep the shooter’s eye drawn to the front sight first. Both sights self-illuminate in low light, giving consistent aim points whether the shot is taken at high noon or after dark. Since the set is fixed rather than adjustable, it installs as a direct, drift-fit replacement for the factory Glock sights.
