> For normal riding-we cut down to a couple of powerful 1w LED's- Cateye EL500 and EL300, and find these adequate. <

I used to use the EL300 and, if the EL500 is the one which is supposed to be a bit better, I used that too (just not positive aboutt he number).

I liked the like okay and it definitely lasted long enough, but the dang mount part on the light itself kept breaking! First there would be a little chip off one side of one end. This would then mean the other side would get more stress so it would soon break. Then the other end would do the same thing. Eventually there would only be a small section in the middle that was holding it and then it would break. I used a number of the 300s with the same result every time. When I ordered the 500 (or whatever it was), I was disappointed that it had the same attachment. However, it did last longer before breaking. I assume that was because the design affected the balance and thus how the stress was distributed.

I strictly ride on roads, though some are a little bumpy because of patches. Wish they designed a thicker plastic attachment.
