Yes the LED strip comes with some 3M tape on the underside and just pastes right on. Could look good in the footwell (if a little bright?).
HIDs are Mars Performance brand. They go by the name Mars Warehouse on eBay. They cost a bit more than other brands but I went with them because in all the ballasts I've purchased over the years, not one of them has gone wrong so I figured its worth the money. If you want a cheaper alternative - look at the link Chris posted just at the top of this very page.
cool thanks, yeah i wouldn't mind spending a bit extra for some that i dont have to worry about catching alight and melting looms!
also, footwell lighting would be hooked up to dome light so fades off, i have been reading wiring diagrams for way too long but i think i have finally worked it out.
