One of the Lopolight wires is a dedicated negative, shared by both lights, and the other two are used to power select either the tricolor, or the anchor light.

Using a set of diodes, and a DPST switch, you can reverse the polarity going to a fixture with two bulbs, but this requires using the negative lead for one circuit as the positive lead for the other. I don't see how you can do this with the three wire Lopolight setup.
Thanks very much for the specific info; that's just what I was wondering about. If the negative leads are connected and sealed together such that I couldn't get a diode in place for each individual circuit, then "that's that."
