That was a very informative link. I did go back through and read it a second time from the first post. From what I gather, he bike mounts lights.

His geometry explanation about the light distribution on the road makes sense. Frankly, I had totally forgotten about "the tunnel effect". When I was in elementary school, I did have a light on my bike then. This made me remember back to the tunnel concept. But, my path had city street lights in that case.
