Red light will not degrade night vision the way white light does. It can also be used by hunters to avoid spooking game during the pre-dawn hours, as deer see poorly in the red spectrum. The filter is also useful for close range non-tactical applications such as map reading as it reduces the intensity of light output. It slips on SureFire and other tactical flashlights and weapons lights with a 1" diameter bezel.
