Where did you get the information that the European break light cluster is different from the north American one?
I compared the two in the parts database. They do have different part numbers, however they both have a total of 3 bulbs. One bulb for the break/turn indicator, one for the additional break light (break force display and is actually located in the part that is mounted in the trunk lid) and one for the reverse light (see below).
Even if you look at pictures from the X6 sold in Europe and compare these to the North American market ones, they look the same....
Part number for the European market:
Left Tail Light: 63 21 7 179 983
Right Tail Light: 63 21 7 179 984
Part number for the North American market:
Left Tail Light: 63 21 7 179 985
Right Tail Light: 63 21 7 179 986
