Yeah, that Philips Saferide is something else. Limited domestic sources for it, but when I first heard about it and started digging up some info off of UK based sites, there are different models rated at different output- including one that is powered by a dynohub.

IIRC, Philips also has a tail light called the Illumi Ring or something like that, but now I can't find any mention of it... Of course, since it's designed primarily for EU markets, it's just a steady beam and lacks the strobe/flash effect a lot of us in the States like having the option of using.
