Now you have the right light at the right time. The Gerber recon light allows four different colors from one white LED without having to change out any lens. Using Gerber's D.I.A.L.--Diode Illumination Adjustable Lens-- technology, this light provides blue, red, green and clear lens options. A unique patent-pending feature that shines four different colors from one super-bright white L.E.D.: white for general use; green for map reading; blue for fluid identification; and red to preserve night vision. Made with anodized aircraft aluminum housing, this black flashlight comes with a lanyard and clip for hands-free use. The recon comes with Gerber's limited lifetime warranty. Long life from one AA battery, included.
