hi i just bought this used 03 White X5 3.0i 49k for $25000.
only package it has were cold weather package.

now i'm thinking to upgrade my head light and tail light to xenon head and clear tail.

i surfed ebay for awhile but couldn;t get much info on how to change it.

many of em from ebay sells xenon light housings only for approx $250 for both.

and h7 hid xenon bulbs with ballast for $120

let say if i buy those housings and h7 xenon conversion kit... what do i need to buy more? or that is all i need?

Just Xenon bulbs with ballast? or anything more to buy?
