(54) Method of operating a multi-function flashlight


(57) A multi-function flashlight (10) device is provided in either an all white light emitting diode (LED) or a colored LED version that allows versatile functionality. The flashlight is fashioned to have an outer housing (12) that includes both an integrated means (14) for interfacing the flashlight with a firearm and a surface thereon that serves as a handgrip. The outer housing (12) of the flashlight is configured to be engaged by a clamping assembly that facilitates integration of the flashlight with standard firearm accessory rail assemblies. The flashlight head
includes a high-output white LED (32) positioned centrally within an optical element such as a reflector. Should the flashlight be a colored light, four other positions are provided around the periphery of the lens that contain colored LEDs (38). The flashlight provides the user the ability to selectively and individually control the mode of operation for all of the LEDs contained therein.
