Just installed these on my X6:

FYI, Umnitza had a super-special 3-wks ago at other BMW forums, for $100/set. I called cause the promo-code doesn't work anymore on the web. The staff, Tim K, told me they are running black-friday for $120 shipped. I asked if I can get that now, he's in the good mood maybe and said sure. So not $199 but $120 shipped.
I had the older gen H8 LED with 4 Cree XB-D LEDs(paid $80 a year ago on ebay) in my 535i, thought those were super-bright already but these are even brighter with 8 Cree XT-E LEDs.
At this point, we hit the diminishing return, cause the optics (plastic rings) inside the headlamp becoming the limitation, not to mention the outer rings always way dimmer.
If only LED headlights are more affordable.
