I've ordered the Dinotte. I really wanted the front light, and when it was on sale, I just thought I'd snap up both. That said, I've run for a long time with two blinkies (one on the seatpost, one on my helmet) that are nowhere near as bright as a Superflash, and that's been fine. I really only got the Dinotte taillight to see just how bright it really is!

There is no question in my mind, however, that bright lights in the wrong hands can be a bad thing. I've almost been sent into fastmoving traffic when approached by a guy with an obnoxiously bright helmet light on the cycle path. He looked right at me, and nearly blinded me - I certainly couldn't tell where the kerb was. The brighter a light is, the more care you have to take that it doesn't become a liability. Those who say "I don't care, as long as it keeps me safe" should consider what an oncoming car will do if it can see nothing but your lights. Think how difficult it is to steer safely in your car when an oncoming car doesn't dip its beams. I've yet to experience this issue with a taillight, but with headlights, it's absolutely a risk.
