Don't even think about anything but European ("E Code") lights. They are so much better, safer, and sometimes cheaper that the US-spec lights. I recently had an accident on my 16V. The quote to replace the RH light with US -spec was $276; Bekkers furnished an E-code replacement for $215.

Either bekker.com or danielsternlighting.com can sell you the parts.
