Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
171 words
A flashlight assembly comprising a. a flashlight bulb, b. a rechargeable battery for energizing said bulb, c. circuitry for providing recharging of said battery, including a charger input, a current limiting resistor, and a light emitting diode for indicating when recharging is taking place, d. circuitry means for selectively flashing said flashlight bulb or permitting continuous operation thereof, said circuitry means including an internal light source, a photocell for receiving light from said internal light source, and a first switch for selectively operatively connecting said internal light source to said battery to thereby provide flashing of said flashlight bulb, or to disconnect said internal light source from said battery whereby no flashing of said flashlight bulb occurs, e. an accessory device powered by said battery, f. a second switch for selectively operatively connecting said accessory device to said battery, g. a casing operatively mounting and containing elements (a)-(f) above, and h. a handle affixed to said casing for facilitating ready manipulation and utilization of said flashlight bulb and said accessory device.
