Now trying to contact seller of second set on 1st post, as there possibly do able. If you look at pic reversing light is white at bottom on tailgate clusters. Plus if like in the pic both sides that go in tailgate heve a normal bulb holder for fog. Aslong as pic isnt of same cluster but mirrored. My german is Zero and im sure translater isnt good.
Seems like others who have bought LED rears, have added wiring from one side to the other, in tailgate to get them to work.
Problem been reversing and fog are wrong way around. Seems like foglight on pass side is MOT fail. So you would havto change them back over to stock, to pass MOT. Might get you pulled also.

So looking onto the second set now.
