Noob question about lights and interior trim

[razrv3]

OK, here's the deal, my X5 came with factory Xenon lights installed, but the ones that are built-in the bumper (don't know how they call them) are yellow which in my opinion looks pretty bad.
My question: is there aftermarket Xenon-like lights (conversions) for those 2 little "bumper" lights, and if yes, where they could be found and how are they called?

Another question: does anybody have light wood trim (walnut?) and aluminum handbrake/pedals installed, and if yes, how does it look?

Many thanks
