For those of us that want to change our standard xenon non Led or halogen headlamp with the Led Headlamp it's possible. But it's still a high amount to pay(under $1000).

You need to get some Led headlamp on eBay they could run from $150 to $400 each or even RS6 which will run over $1000 each and a retrofit kit upgrade from xenon to xenon facelift head lights w/led which runs about $460 with shipping.

There is also retrofit kit upgrade from halogen to facelift head lights w/led which run about $590 with shipping. Link: Audi A6 4F - bundle facelift head lights (LED) - BKS-Tuning

For $750 I'll thinking.

But just shooting this info just in case someone is looking to upgrade the headlamps.

 

But you would also need to install the headlamp wash system?
