The SureFire M952V White/IR LED Millennium Universal WeaponLight attaches by means of an integral throw-lever clamp to long guns equipped with a Picatinny rail. The M952V White/IR LED Millennium Universal Weapon-Light by SureFire utilizes one sealed LED unit to produce both brilliant white light and invisible infrared radiation for use with night vision devices. The white beam of this weapon flashlight is configured for close- to medium-range applications. Changing back and forth from white output to infrared output is accomplished by a push/twist action on the M952V head, which self-locks into the selected output mode. The SureFire WeaponLight 's tailcap switch assembly features a momentary/constant-on pushbutton switch and a momentary-on tape switch (7-inch cable) that attaches to your preferred location via self-stick Velcro backing.
