Abstract: A multi-function flashlight device in one preferred embodiment comprising a housing assembly having a tubular member for gripping the device in a user's hand, a control housing coupled to the tubular member, and a lamp housing coupled to the control housing and having a light source mounted therein. The light source has an optical axis that is substantially perpendicular to a longitudinal axis of the tubular member. Batteries are housed in the tubular member. A control panel having a keypad overlay is mounted in the control housing. The keypad overlay includes a plurality of control buttons. A driver board in the control housing receives signals from the control panel and control the operation of the light source. The plurality of control buttons are manipulable by a single digit of the user's hand while gripping the tubular member.
