Having just bought a 1998 A6 2.4 I fancied upgrading the lights to Xenon lights. Having looked around I came across a company called HIDS4U (www.hids4u.co.uk). It is rare that I am impressed by the service and the product that a company offer but in this case both are fantastic (no I don't have shares in them!). If anyone wants better lighting on their car contact HIDS4U as it makes a huge difference and for the price it is a bargain. Really easy to fit as well.
