Surefire fm35 red filter - SureFire FM35 Red Filter for flashlights with 1.25" diameter bezel (Z2, C2, C3, G2Z, G2, 6P, 9P )

Good product. Easy to install and once is placed on the flashlight, it won't come off. Easy to use, the red filter can be flipped with a thumb to use the regular beam of the flashlight. Won't mess up your natural night vision as much as the white light would.
Pros: Best value for the buck.
Cons: None.
