Recently, Autopax developed a new trailer light power module.
It works for 12-24V multi-voltage system, providing an independent power source to the trailer lights.  
It has seven wires in and six wires out; + and – input makes it an independent power supply.  
Thus it won’t interfere the electrical circuitry of vehicle and alert computer system there is a fault.
