There are a few different threads on the interior and exterior LEDs. I did make a short YouTube video on how to change the bulbs as well which you’ll find in the threads. The vanity bulbs are simple to change and inexpensive.So I had the factory LED's installed today. I didn't realize that it only included the 6 dome/map lights. I'd like to do the vanities and the light in the trunk area. Any advice/tips?
