I think there was either a thread on one of the forums OR maybe an article in a magazine like BMW ON or American Motorcyclist(AMA) that gave some research results that bright lights in daylight really "washed out" the depth perception of oncoming traffic or say, another driver sitting at an intersection. In other words, the extra bright light diminished the ability of the eyes/brain to see just how close/far the vehicle is from the driver. IMHO I agree with the concept.
As to the law, it's a state-by-state thing in the US.
Oh yeah, South Carolina just passed a law that "after two minutes" a light doesn't change for a motorcycle, you can "proceed with caution". I'm still looking for my stopwatch.
