I don't think the law has changed...but the BMWs seem wired for left and right lights. This switch takes advantage of the adaptive brakes that have a brighter blast of light on hard, sudden braking. When the switch is engaged, both left and right lights illuminate, and believe me, in fog these really cut through the soupy fog and let people know you are there.
