Night sights are specialized aiming devices designed to enhance visibility in low-light conditions. They typically use tritium or fiber optics to illuminate the reticle or sight picture, allowing shooters to acquire targets more easily in darkness. Night sights are commonly used on firearms, such as handguns and rifles, to improve accuracy during nighttime operations. These sights come in various styles, including iron sights and red dot sights, and are often installed as aftermarket upgrades. Many law enforcement and military personnel rely on night sights for tactical situations, while civilian shooters may use them for home defense or nighttime hunting.
