2000 BMW 323i Headlight Question

Hey All,

I have the stock halogen lights for the 2000 BMW 323i. I want to put xenon and angel eye in, but an wondering what i need to do this? looking for suggestions on conversion kit, will the halogen housing suffice for the xenon lights or do i need new housing? and depending on the answer to that question i suppose would decide the answer to what kit i should pick if purchasing this angel eye conversion kit...http://www.umnitza.com/orion-lite-60...es-p-5686.html

Any help/ previous experiences doing so with the same type of vehicle would be appreciated

Thanks
