A consideration: Even with very bright lighting, you do not see everything nearly as well as during the day. I much prefer riding routes I know well so I have a very good idea of the road edges, cracks, potholes, etc. That said, the occaisional no-so-fast ride at night can be a blast! I did one of my daytime loops last summer on a full moon. Wow! I know those rides really well and still, at night it was a new experience.
