Alas, they are different.
Perhaps not hugely, but there is a small plate thingy on the US ones that would need to be removed (if I've got that the right way around) anyway, point is that to go from US to Euro, you'd need to mod your US ones such that you couldn't easily change them back again. Whilst the bezels aren't cheap, you may feel that buying the ones designed for the Euro lights is worth doing. I made the change and got new bezels, plus the new chrome looks great.
