Okay, so I work at a BMW dealership as a service advisor and here’s what I found after some digging. Yes, they are different physical parts, however the connectors are not different between EU and NA spec vehicles. That being said, there is an extra conductor in the connector, so at the bare minimum, you’d have to add a pin and wire to run to the appropriate location on the BDC. In addition to that, there are noise interference filters on the upper part of the rear hatch that the taillight wiring runs through, so you’d have to bypass those, do the appropriate coding, pin the connectors, run the wiring, then fit the EU lights. I’m toying with the idea of doing so myself since I have the technical documents showing wiring, pinouts, etc… my M50 arrives here in about a month or two. Made it to Bremerhaven today and missed the boat, so it’ll sit for the next 3 weeks till the next gulf-bound ship makes it over there to pick up mine
