Default Model A tail light installation

Anyone install a Model A tail light on the side of their bike? I have one with 2 wires and 2 single filament bulbs. One wire is the ground and the other is the power wire and lights up both lights. I am having trouble figuring out how to get one to be a stop and one to be a park light?
Any ideas?

I figured that is how this one would be, but the bottom wire is black and has to be connected to the black wire from the harness(i am guessing ground). The other wire I an using is the blue wire, which lights up both top and bottom constantly. I cannot figure out which one is the brake light because the only two wires that will make any thing light up are the blue and black combo.

This may seem like a redundant question, but do you have dual filament bulbs? Have you checked to see what wires are coming out of your existing tailight? I'm running '59 Caddy taillight/stoplight combos but they have 3 wires.

I used to have 2 single filament housing which I replaced with one dual filament housing. Single(tail/plate) on bottom and dual(tail/stop) on top. The only one I can get to work is the single filament(tail/plate). The dual won't work at all.
