Hi All, I know lights are talked about a lot, and many recomendations have been made, but it's never really clear if the lights people are happy with, are to see, or be seen. In terms of visability, I've got a cheap LED flasher, which drivers seem to notice quite easily. It does the trick. What I want to know is, how many watts or candle power is required to see a safe distance on a totally unlit path riding at say, 25 - 35 km/h? Before parting with potentially hundreds of dollars, I'd like have some idea so that I spend enough to get something decent, but not necessarily break the bank for somethingthat's overkill.
