The good folks at the San Francisco Bike Coalition have a new video out (you may remember their training video for the police regarding bike matters) about riding in the rain and at night. Again, it's well done; plus it has "Riders on the Storm" by the Doors, one of my favorite songs, as the background music.
A note on the video:
While San Francisco requires a white front light and rear red reflector for riding at night, Columbus requires a front white light, a rear red light, AND a rear red reflector (keep in mind that most of your rear red lights will also function as reflectors).
People, not speed.
