I wasn't in a downtown area...
I was here...
I was riding in the bike lane
as required by state law.
This could have been the view from the motorist's sideview mirror of my approach (but it would have had more cars).
I was passing vehicles on the right as they were tied up by the stop and go nature of the rush hour traffic. It is possible that had I been using a light that was visible in daylight, perhaps the motorist would have seen me approaching when he looked into his side view mirror, and paused for me.
No matter what, it couldn't have hurt to have a headlight on when I was riding.
