Trijicon 3 Dot night sight sets are designed and assembled with the optimum combination of strength and safety. The patented aluminum cylinder and sapphire lens construction cannot be equaled. The brightness obtained from the tritium content is focused through the sapphire lens to give the maximum possible illumination. Because the sight blades are machined from steel rather than cast, their strength is unsurpassed. Trijicon night sights are the brightest, strongest and safest.

White Rings: All Trijicon Tritium Night Sights feature a white ring around the glowing dots for unequalled daylight visibility.

Silicone Rubber Cushion: Gives additional shock-protection to tritium filled glass lamps within the aluminum housing.

Trijicon Tritium Phosphor Lamp: Glass lamps in Trijicon Night sights are filled with pressurized tritium gas glow bright green, yellow or orange at night.  The lamps are guaranteed to last 12 years (green or yellow lamps).

Protective Aluminum Cylinders: Contains and protects the tritium gas filled lamps from heavy recoil and harsh cleaning solvents.

Sapphire Window: Each Trijicon Tritium Night Sight Lamp is capped with a Sapphire Jewel which helps to evenly distribute the light from the tritium lamps as well as protect it from solvents and puncture.

Green lamps in Trijicon Tritium Night Sight Sets are warranted for 12 years from the date of manufacture.
