I also have the Cateye LD600 and at one time it was the brightest LED on the market...well it's still the brightest rear tail light I've seen used in this town that doesn't believe in lights of any kind! My LD600 is now 5 years old and it still works very well and I still get comments on motorists as to how well they can see me.

The new SuperFlash is a brighter light then the Cateye LD1000 though and actually cost less then the Cateye. A new rear light from BLT called the Super Doppler DX may now be the brightest taillight on the market even more so then the Superflash.

By the way many countries prefer a non blinking rear light for cyclists and Germany forbids them; in America we don't care if it blinks or not just as long as you have one. Most safety people will tell you that it has been found that people tend to underestimate the distance to blinking lights, and also that drunken drivers are attracted by them, and there is evidence that they are harder to place than a steady light; I think you should keep your light and use only the steady mode, that's what I do, only my barends blink and that's only to save the little button batteries.

I also use a amber xenon flasher on the front along with my headlight because bicycle headlights are nowhere near the size of a cars so again motorists are unsure of the distance you are from them or don't see the light at all because it is so small; so the flasher gets their attention first.
