B7 S4 Cabriolet - Xenon Headlight

[Kayeabl78]

Afternoon,

I have a headlight bulb (xenon/HID type) that has failed on my B7 S4 cabriolet.

I have found a good few guides on how to change them, but what bulbs do people recommend and where is best to buy from.

There are various cheap versions on eBay and Amazon, but perhaps i should stay away from those!

Any pointers appreciated

Thanks

I'd be going to Halfords or other motorfactors as Audi will charge you a fortune.
