Talking about xenons, anyone recommend a brighter/whiter bulb for an A5? I posted it in the show us your car thread rather than in here, sorry.
Fox as you stated in the other thread, light output peaks at around 4300k, is it worth changing them or just leaving them stock? I don't really want to lose light output for the sake of them being a bit whiter if that's the case.
Are they factory Xenons? I would leave them alone if they are.
