My LBS told me that the Cateye 1000 and the SuperFlash can easily be seen in broad daylight and the SuperFlash is the brightest of the two. Granted if you can afford a $140 Dinotte tail light then go for it, but from pictures I've seen it has no side lighting just a spot of red on the pavement, thus you would need another blinky (or should get) to illuminate the sides of the bike.

I guess my question would be why pay $140 for one tail light when you could spend $60 and have 3 SuperFlashes for $60 and form the triangle I wrote about earlier using seatpost and stays?

If I was on a limited budget and thought maybe I could afford the Dinotte but may have to scale down a front light, then I would far rather pay $60 for 3 rear SuperFlashes and spend the left over $80 either towards a better front light or add $80 more to a budget I had for a front light.
