This is one of those situations where UK's "rule by law" model could actually be super positive. Make a law restricting brightness and put police and cameras onto ticketing drivers who needlessly burn their highbeams when lowbeams would suffice. The old halogen-warm colors were better, too. You don't want "area denial" lighting on your everyday ride.
