Ok, so this is completely the wrong time of year to start thinking about this, but still, I thought some of you might have ideas from this winter's commuting.

Briefly - what do you think of the really bright bike lighting systems available now? Sorry, haven't read up so I don't know the jargon, but this winter I've seen several commuters sporting BLAZINGLY BRIGHT lights, so bright that I can't see if it's a bike, a motorcycle or a car with only one headlight approaching. A friend of mine just bought one of these (Light and Motion something-or-other), which I thought were designed for lighting up unlighted trails and gravel logging roads, but he doesn't even ride places like this in the dark, he's mainly a commuter like me and is going to use it commuting along roads and bike paths with (some) lighting.

I'm out of lights at the moment. I don't really want to get one of these, since it bothers me when other people use them and I can't see the rider. But there's no doubt that one is EXTREMELY visible and attentiongetting wearing lights this bright. Any opinions, either if you've used them or just seen them?
