That might explain why supernova rear doesn't match other fronts ... the capacitor in the rear doesn't charge. I had something similar when I rigged up two rears in sequence, in that the latter rear in sequence wouldn't have the standlight.
It has to be said that very few really good rear lights seem to exist. I have a B&M mudguard one (secula) that I'm constantly knocking the red cover off, have resorted to using some wire to strap it on.
I have two b&m rear lights wired in parallel (this may be the key) and the stand light works on both. Must say, I've found the secula really good, just needs a shorter bolt!
