      What is LED CANbus?

      Some car models present particular challenges for LED-based retrofit lamps. When upgrading your car with LED retrofit bulbs, challenges may occur such as an error message on the dashboard, flickering or dimmed lights. These error messages don’t mean the LED bulb itself is faulty.
