On Christmas day I was driving after dark and saw a cyclist was going the other way. Yes, on the correct side of the road. He had a white light that made him easy to see, and a red blinkie on the back that was making him visible too.

The thing I thought very interesting, was reflective tape on half the diameter of each wheel. So as the wheel spins it gives off a slow flash/wavering effect. It was very easy to pick out something moving was there from quite a way off.
