i installed the led bulbs to license plate, but the led bulbs flashies or there is an error showing on the dashboard , why?
For some newer European vehicles such as BMW, Mercedes, Audi, Volkswagen, etc, they all have a very smart and sensitive on board computer, OBC. The OBC will notice the LED bulbs because LED bulbs have lower wattage comparing with original fillament bulbs. In order to eliminate the flash problem and bypass the OBC error showing on the dashboard, you will need to add resistors. Or purchase our LED bulbs with built-in-resistor to prevent this issue.
