[quote=Geckoboy]I read that during my research into HID lights and noticed that if you follow the link to ECE regulation 48, the USA does not participate in it.

What else is new!

QUOTE=Geckoboy]Also, I noticed that in my previous 2003 Acura TL-S, the HID headlights were fixed (not auto leveling), and no lens cleaning system in place.

Because they are designed to meet US regulations which don't require them.

North American regulations and technology often lags far behind the rest of the world. Manufacturers here have always preferred to sell sizzle rather than substance. For example it was many years after superior radial ply tires became standard in Europe that NA manufacturers switched over from the inferior bias ply type they were selling here.

Okay, that's my rant from the moment
