Bad news for me ... i'm told that the EU spec X5M headlights ARE different to US spec, and that the DRLs i've received (see pics from previous posts on this thread) can't therefore be fitted to my car
c'est la vie ... i guess
any US members want a set of these DRLs, they're free to a good home in a "pay it forward" kind of forum way (admittedly they only cost me $180, but hey)
