It is my understanding that BMW's "no-dazzle High Beam" feature, which is part of the full LED lighting package in some countries, does not work for USA market cars. If that is so, I wonder whether this feature in fact can be coded on a USA market car. This 5AP "option" sure sounds like BMW were forced to decode it for USA.
In another (model) forum, someone stated that the USA headlights are physically missing a "magic roller" that makes this no-dazzle possible. I am not inclined to spend $1,900 on LED headlights if most of the good stuff has been coded out - and cannot be re-coded back in to functionality.
