The KM2 bezel assembly provides both white light and infrared illumination from two 123A batteries when used on an M600 Scout Light(R). Select the appropriate spectrum for the mission by simply rotating the bezel. This small, rugged Weapon Light features SureFire’s proprietary TIR lens, a far-reaching, high-intensity beam with ample surround light. Upgrade your Scout Light(R) to 350 lumens and 120 mW of infrared illumination with the KM2.
