If you’ve been looking into purchasing an LED Bulb you might have noticed the terms ‘CANbus control unit’, ‘canbus canceller’, or even ‘resistor’ or ‘adapter’. But what does this mean?
To put it simply, a CANbus canceller is a small cable and adapter system, which is installed in between the wiring of your vehicle and the LED bulb. Because LED car bulbs use a lower wattage than other bulbs, the CANbus canceller helps to increase the current safely and without damaging the bulb. This will ensure that your vehicle doesn’t bring up any error messages and the LED can work as expected.
