In general, I think that European cars were designed for a look that involved big glass headlights, and in order to conform to American D.O.T. requirements, they created a second light design for the then-required US Sealed Beam headlights. So I think that the idea behind the desire for Euro lights is that Euro lights are the original and more pleasing design, and the American design is just because the U.S. required it. The same can be said for US bumpers... Certainly a lot of compromises were made to accomodate US Bumper requirements. Yech!!!
