Nighttime and low light shooting tests prove sights equipped with these glowing dots are easier to see and more accurate than instinctive shooting with standard black sights. Rugged, heavy duty, Traser®, luminous, 3-Dot tritium lamps provide their own long-lasting energy source. Lamps are mounted in silicone-sealed, metal cylinders to give maximum protection from breakage or leakage. Polished sapphire, crystal windows give a bright, crisp and perfectly round aiming dot in low light. Inlaid white rings around each sapphire make the sights appear as standard white dots in daylight. Very narrow blades do not have the white ring and will look more like a plain black blade in daylight. Most can be installed in factory dovetail or sight base.

Trijicon Bright & Tough™ Night Sights are three-dot iron sights that increase night-fire shooting accuracy by as much as five times over conventional sights. Equally impressive, they do so with the same speed as instinctive shooting - and without the need for batteries. Housed in a metal body and cushioned within silicone rubber, Bright & Tough Night Sights feature a unique shock-resistant design. Each lamp is capped with a sapphire jewel to help evenly distribute the light while protecting the lamp from solvents and puncture. Contained within aluminum cylinders for additional protection, the lamps are mounted on silicone rubber cushions to withstand shock and heavy recoil. Green lamps are warranted for 12 years from the date of manufacture.
