The Meprolight Tru-Dot night sight set (brand part number 0102243201) pairs a green tritium front dot with a yellow tritium rear dot in a white outline, built to fit Glock 17, 17L, 19, 22, and 23 pistols. Made by Meprolight, these self-illuminated sights glow without a battery or charging light, giving a consistent aiming reference whether you are shooting in daylight or total darkness. The three-dot picture is identical day or night, so there is no mental transition needed when light conditions change. As a direct replacement for factory Glock sights, this set drops in with only minor modification for a meaningful low-light upgrade on a duty or defensive pistol.
