The outer section sub-assembly at least... as explained by the poster who tried to retrofit the old/legacy EU tailights on a US Model 3... these will most likely not be plug and play, just as the EU units are not.
Aside from the new assemblies, software config needs to be toggled over which SCs and MS will most probably not want to do on elective retrofits. Too bad.
