Well that sucks. I own a Saferide and I really like it a lot. Why didn't they just simply sell the rights to someone else to make instead of just throwing the whole thing down the drain!
The tail light situation...I never saw the Lumiring in action since it's sold mostly in Europe and intended to be put on rear racks instead of seat posts or saddle bags like American sold tail lights are designed to do, so I can't say how bright it is, but I can say that Light And Motion Vis 180 (not the Micro) is extremely bright and it's easiest the brightest tail light I've seen where I live. I doubt the Lumiring is as bright as the Vis 180.
