Have you done license plate lights? I got some of those ebay ones that come in with enclosure itself, and they work, but they are just way too bright. But when i try the C5W led bulbs then the car shoots an error at me even tho it says they are canbus.not done brake, but pretty much everything else with no errors.
I suggest using the forum sponsor trups but I live over the pond so check out deautoLED. I have all their bulbs both inside and out without any warnings so plug and play.
