A couple of years ago, I order tail lights from BusDepot. The long and
short of it, was that I wanted domestic style, and they kept sending
european style (and neither of us realized there was a difference at
the time).  I thought they were defective, they insisted they weren't.

It wasn't until they got one out and started comparing them to a
domestic one that they realized what I had noticed right
away....European models don't have the extra chrome reflectors on the
inside of the turn signal section of the tail light plastic. US style
ones do.

it was a frustrating experience that could have been solved had they
asked me for digital pictures. Just be happy in this case, they really
are trying to reduce the back and forth aspect to your purchase.
