Looks really good.
As asked above, are the bulbs hard to replace and do they look "LED white" or do they have a blue-ish tinge about them?
Edit: Just read the manual, and it seems you just need to unscrew a protective cap under in the engine compartment. I'm sure on the E90 you have to get at them from the wheel arches! I think the 7500K may look slightly less blue...
