To all of you new commuters. The whole thing is TO BE SEEN. The thing is to at least have a tail-light in the back. I have three of em'. Here in Columbus we have a PerformanceBike shop, which happens to have them on sale right now. I have red/white reflective tape on my fenders, with a homemade mudflaps http://phred.org/~alex/bikes/fendermudflap.html with a big reflector on the rear. Up front, I have three headlights. A Cateye HL-500, and two viewpoint 5 flare's. I didn't want to spend $300 on headlights, and they light up the road enough for me. All of this in addition to the Showers Pass rainjacket, which has lots of reflectivity to it. I ride everday, rain, shine or snow. And I notice the cars going around me. PS. a mirror helps alot too.
