If you were going to buy either a Dinotte Taillight or headlight, which would you buy and why? I don't think I'm ready to plunk down the $400 on both right now, but I want to give one a try. The roads I ride on at night are pretty well-paved so keeping an eye out for potholes isn't that important. Right now I have no lights, and don't want to go through the whole "buy the $20 light, then the $40 light, then realize you should have gotten the good light to begin with and you basically double your costs" thing. So what should I get first?
