My night riding setup: Use streetlights to see where I'm going but flashers front and rear as well as wheel reflectors to be seen. Some reflective tape on bike and reflective material on cycling clothes as well. Ride a mountain bike with 1.9 road tires and a road cassette. Forget about obeying the law-If I didn't spend half my time on the sidewalk I'd be dead.
I live in a reasonably safe city but I wouldn't ride on the bikepaths after dark unless I wanted to *****, robbed, or murdered.
