A4 B8.5 DRL LED upgrade


Registered User
Hi, I recently purchased an A4 Avant SE Technik (14 plate) which I am very happy with.

What I wanted to know is how easy it would be to change the yellowy halogen DRLs to white LED? (Edit - unless white Halogen bulbs look as good?)

I have searched and seen you need to cut some holes which petrified me, but I saw something on a bulb site suggesting that on the B8.5 you don't need to cut holes, simply switch bulbs?

Does anyone know if this is the case and if so are you allowed shop recommendations?

Finally how can I be sure I have a B8.5?

Thanks for any help
