Abstract: A portable lighting device includes a power source, a controller, and a load. The controller comprises a power input terminal which is electrically connected to the power source via a switch. The load is electrically connected to a power output terminal of the controller and is capable of providing a feedback signal. The controller regulates the power being provided to the load according to the feedback signal and a conduction status of the switch.

Abstract: A circuit for driving a vehicle lamp includes a current path coupled between a power line and ground, and a monitoring unit coupled to the power line. The current path includes a dummy load. The monitoring unit can monitor a testing signal applied to the power line. The testing signal can test whether the vehicle lamp operates properly. The monitoring unit can conduct the current path to enable a current to flow through the dummy load to ground to decrease a total resistance of the circuit if the testing signal is detected.
