SureFire F05-A Red Filter for 1.125" Diameter Bezels. The F05-A is a red filter for flashlights and Weapon Lights with a 1.125" bezel diameter. 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 pre-dawn hours - deer see poorly in the red color spectrum. The filter is also useful for close range, non-tactical applications - such as map reading - as it reduces the intensity of light output.
