The Aviator features dual output with a secondary yellow green colored LED for specific tasks. A classic SureFire design, the dual-output Aviator flashlight features a primary white LED and secondary colored LED in one sealed head, both focused into a useful beam with ample reach and surround light by our proprietary Total Internal Reflection (TIR) lens. Pull and twist Aviators self-locking selector ring to set it to white or colored light, no filter required; a system-disable setting prevents accidental activation. Show your discriminating attitude at any altitude. Includes battery. Yellow-Green is complementary to the color spectrum used in most aircraft cockpits.
