Green-powered lights on bikes aren't exactly new - dynamo ones lit by pedalling have been around for over half a century - but this is the first time I've seen a solar-powered one. The bulb's a low-power, high-visibility, long-life three LED job and it charges constantly while you're whizzing about via a simple solar panel on the top. There's no quoted charge time, but there is a mention that it'll run for 15 hours continuously. Which is useful if you were planning on doing the London to Brighton bike ride four times in a row during deepest darkest winter. The torch takes standard batteries, so buy Ni-MH ones. It's on sale for a very cheap £20 from Ecotopia.

Saw your review on the hokey spokes bike lights: do you use them during the day time? Do they provide much visibility during the daylight?
Hi Christopher, generally I've only used them at night. In daylight they're no brighter than your average LED light, but because of the flashing patterns they tend to catch a driver's eye in the daytime. So I guess the answer to your second question is 'a little'.
Hi,
I was wondering where to get one of those bike solar bike light?please write back
