The bulbs have canbus functionality and better compatibility, but there are still some cars that have super flash or error codes or don’t work. The bulbs are equipped with Canbus, but there are still a few vehicles that may need to add an additional load resistance decoder to bypass the error code/flicker/not working issue.
