I've wanted the LED Union Jack tail lights since I first saw them. Obviously these aren't OEM (since MINI doesn't make them for my model year), but they're still damn good and they fit well. The driver side went in easily; the passenger side not so much. The hardest part was getting the old units out because of the layout of the retaining screws. I may need to redo the passenger side once I have the proper tools to loosen and tighten the nearly-inaccessible screws that hold them in place.
Also, the backup lights are confusing. The passenger side is white; the driver side is red. At first I suspected that something was wrong, but going back to this—and similar—sellers' pages for the most part they're all showing this same configuration. (I think it's designed to be used as a reverse fog light, even though the car had no rear fogs.) Still, after everything was back together I wrote the seller to verify this was indeed the case and that I didn't get an incorrectly wired unit.
Adding to the ease of installation, the lights needed no re-coding of the onboard computer, something I had been worrying about. They really were plug and play.
Sweet! They look great.
