A portable and rechargeable lighting apparatus includes an elongated housing having a radially-central cavity extending longitudinally along the elongated housing; one or more light emitting diodes (LEDs) affixed to a surface of the elongated housing and operable to emit light; one or more rods operable to extend coaxially from the radially-central cavity; one or more hooks coupled to distal ends of the respective one or more rods; and a battery operable to power the one or more LEDs.

An automobile auxiliary lamp includes a lamp and a connector. The connector is installed at a proper location of an automobile and connected with the terminals of related control devices of the automobile for receiving electricity supplied by the automobile, and the lamp is engaged with the connector. When a user operates a related control device of the automobile, the lamp will synchronously be triggered through a control connecting line to function and emit light, able to enhance warning effect of the automobile lamp. In addition, the auxiliary lamp can also be removed from the automobile to be independently used as a common illuminating lamp, enabling a user to use the lamp for various purposes.

The invention relates to a multifunctional vehicle-mounted flashlight. The multifunctional vehicle-mounted flashlight comprises a power source module, an LED illumination module, a signal detection management module, a power source management module, a charging module and a control module. The power source module is used for providing electrical energy for the LED illumination modules. The signaldetection management module can be used for receiving working signals of the power source module and external input signals and sending a corresponding instruction to the power source management module, the charging module or the control module. The power source management module is used for adjusting a working state of the power source module to make the power source module switch between a normal working state and an energy saving state. The charging module is used for supplementing electricity to the power source module when the charging module charging module receives external input charging enable signals. The control module is used for adjusting color modes, brightness modes and flashing modes. By means of the multifunctional vehicle-mounted flashlight, working signals of the power source module are detected and managed in real time, and the power source module is made to be switched between the normal working state and the energy saving state, and electricity is supplemented toa power source in time.
