Beretta Cougar 3 Dot green front & green rear night sight set for models 8000, 8040, & 8045. Green lamps are warranted for 12 years from the date of manufacture. Trijicon offers a choice of illuminated dot colors, to suit individual shooter preferences. Trijicon Night Sights are available with green, yellow, and orange aiming dots. Trijicon recommends green dots because they are the brightest lamps. They are best for targets in low- and no-light shooting conditions. However, because some shooters prefer greater distinction between their front and rear sights, Trijicon also offers yellow and orange dots for rear sights. Trijicon recommends yellow over orange for the rear dots because yellow is brighter, lasts longer, and therefore carries a longer warranty. 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.
