Hunters use blue light filters to track wounded game at night. Blue stands out more distinctly against foilage when viewed under blue light. This filter is also useful for close range non-tactical applications such as map reading because it decreases the intensity of the beam. Slips on to all SureFire and other tactical flashlights and weapon lights with a 1" bezel and produces a smooth beam of blue light.
