1) I live in Brandon (Suffolk)
2) As far as I know, you can use the adaptive xenons in a halogen-fitted car. The only thing: My understanding is that if you don't buy some sort of conversion kit, the adaptive part of the lights won't work (the lights won't move as you turn the steering wheel). The xenon and angel eyes will be the only things that work.
All of this is qualified with a strong "I think so" - 'cause what I know about BMW lighting is ... well, not much! However, I went and browsed this forum and found some links that support the thought that it'll work:

Hope this helps.
