Yep, you cant buy an M135i without xenons, all come stock from the factory with them...
Good choice of bulbs here for those with xenons, or going to retrofit

Personally I've always stuck with Philips, but might have to give the Osrams a run sometime in the future. For everyone else who has not yet ordered their car,
always tick the xenon box. Once you try them you will never ever go back to halogens...
