well all you need is a HID kit. at 4300k, you will have a stock looking xenon set up.
The problem with HIDs kits is that they create problems in a halogen housing. As the Eos has projector lenses already, all you need is the bulbs and ignitors.
The genuine VW xenon kit will not be hugely diss-similar to your existing headlights + Hid kit. (obv its missing auto level and washers, but you would be with those angel eyes anyway)
