Vehicle auxiliary lighting system

Abstract

A vehicle auxiliary lighting system is disclosed to address the known problems of increased load on the vehicle's electrical system or shortened battery life. The system includes: a voltage detection module electrically connected to a vehicle battery for detecting the battery voltage and generating a voltage signal; a control module receiving the voltage signal from the voltage detection module and outputting a control signal based on the voltage signal; a power regulation module generating a drive current based on the control signal output by the control module; and a lighting module receiving the drive current from the power regulation module. The control module determines the vehicle battery voltage based on the voltage signal and controls the drive current of the power regulation module to adjust the output power of the lighting module. This improves ease of use and provides dynamic power regulation.
