I used a combination of front lights depending on the situation and two rear lights - a CygoLite Hotshot mounted on the fender and a Blackburn Flea on the tool bag under the seat. I would agree that reflective tape is a good addition. I've taken thin strips and wrapped them around 12 spokes on 36 spoke wheel. My neighbors tell me when I pull in at night they know who it is from a block away by the "circus" wheels, as they call them.
