That's not a bad idea either, as a light that is blinking gets more attention than a light that is steady, and a light that is moving with my head would get more attention than one that is (relatively) stationary on the bike. But I'm not sure how my helmet would accommodate a light; I could probably rig something up with a velcro strap through the vents, and I'd also have to use a rubberband, because just using the "pocket clip" to hang this light on the strap on the back of my seatbag does not work, it falls out with the slightest bounce.
