For a time, I worked at processing accident data at NHSTA. We collected a lot of data and first sorted out the motorcycles that either were in states that required the headlight on or those that had the switch that did not allow the headlight to be turned off.

It was a manufacturer choice then, but it is a DOT rule that motorcycles not be able to shut down the headlight(s).
What we did run into that was neat was that the European cars with a fog taillight (an auxiliary bright taillight that comes on with the fog lights) were vastly more likely to be rear-ended in the daylight if they had the fog lights on.
The best we could figure was that this was a result of the fog taillight reducing the impact of the brake lights.
Isn't data fun?
