Abstract
A flashlight assembly including a flashlight bulb and an accessory device, such as a two-way wireless radio, operated by the same rechargeable battery. Recharging circuitry provides for sure, ready recharging of the battery, and low-current drain flashing circuitry provides for long flashing life for a given battery charge. All of the components are mounted in a casing, the casing having a handle affixed thereto for facilitating ready manipulation and utilization of the flashlight bulb and accessory device.
