Hello, i have seen all topics on doing PFL to FL led taillights. But have anyone did halogen to led taillights on A3 8V FL ( 2017+) Thanks!!
You can do, but they are about £1000.00 per light Aftermarket LED are garbage and not suitable for the reflector halogen housing.
If you have a saloon, I have a complete retrofit package that allows dynamic taillight function for sale. Let me know if your interested.
