ABSTRACT OF THE DISCLOSURE A recharging circuit including a diode and a battery seri- ally connected and coupled in parallel to a power source includes (a) a first indicator connected across the power source and illu- minated by a charging current delivered by the power source; (b) a second indicator connected between the power source and the junction of the battery and diode, and which is illuminated by discharge current delivered by the battery in the absence of charging current from the power source, and (c) a transistor cou- pled across the power source and to the second indicator, and being biased by charging current so as to prevent illuminated of the second indicator. The recharging circuit is included in a rechargeable flashlight and the first and second indicators are formed by a single bi-color light emitting diode.
