I had my rear light attached to the v-brake boss on my bike along with the brake itself. In that position I think it is blocked too much by the wheel and very low down, and entirely blocked by my pannier when I'm using it. I also had it mounted on the left side, which would be good almost anywhere except in NYC. In NY we have mostly one-way streets, and we usually ride on the left, so the light isn't visible by drivers approaching on the right. And since Dirk sent me a left side mount, I can't just swap it over.

Instead, I've attempted to attach the light to my rear rack on the right side as far back as I can so that the light would be visible over the wheel. That to me would be an ideal position. I just haven't found a good solid way to mount it yet. I used a round clamp to the round rack frame, but it kept slippin' and slidin'. I need a mount that would straddle two of the rack rails and then wouldn't move.

As for visibility, I had an original Magnic Light and would get frequent comments about it from both drivers and other cyclists. it was very noticeable. It's a shame I lost it. I expect the same from this new improved version.
