I have a supernova and don't really want to pay for a tail light when I have a stack of B&M sitting in a drawer. I have seen hints that people have done this. I'm also thinking about DIY'ing a light using one of my cree XRE red LED's for this. I am curious how Supernova does their circuit. Seems like they just have a limiting resistor and 3 Vf to limit the current. I probably would just use one XRE, otherwise it seems like it would be blinding.
