Why there will be error showing sometimes you installed the LED?

l          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 stock tungsten 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.
