there was a thread here recently where we talked about a taillight for supernova. They rectify the voltage which includes the standlight. So they probably don't want to be responsible for helping make other lights work. I still haven't tried it, but another poster said that a B&M light works if you hook it up right. The supernova lights appear to be very simple, 3 leds and some resistors. Although I've never been able to verify this from the pictures I've found online
