FM45 This product has been discontinued. Red Filter for 1.37" Diameter Bezels
The SureFire FM45 Red Filter produces a smooth beam of red light that will not degrade night vision as white light would. Hunters use the red filter to avoid spooking game during predawn hoursdeer see poorly in the red color spectrum. The filter is also useful for close range, non-tactical applications such as map reading because it reduces the intensity of light output. Applying thumb pressure to the locking tab releases the cover; a spring mechanism keeps the open cover out of the way by holding it flat against the flashlight. A cam-locking lever keeps the entire unit securely attached to the flashlight.
