So it would seem that they are not required in the US at present. Otherwise, they'd be on every car and truck sold here. The European thing is funny--my Jetta has them (and I hate them, because I'm replacing low beam bulbs way more often than in any other car I've ever owned,) but my wife's Range Rover doesn't have them. So it's not like all European companies are just putting them in everything. The Rover does have the cool "euroswitch" headlight control with the rear fog lights. That I do like--but I like having the option to turn them on and off. I wish VW would do that. I really hate having features in my car that I can't control...
