Wiring Single Bulb Tail Lights to 7 Pin

I'm in the process of wiring the tail lights on our rig--old single bulb Bargman 98s. So the brake/turn and running light wires both need to be joined to the socket's hot wire, yes? Well, I did this and, when testing with a 6v battery all the lights (running, LT/Brake, RT/Brake, etc.) come on together regardless of which wire I test. Looks like the running light wire is completing the circuit in all cases. I've got the ground wire running to the negative terminal of the test battery for now. What am I missing/doing wrong?

Tail lights are one circuit, and stop/turn is another.

If there are two single filament lights on each side one will be a tail, and the other will me stop/turn, otherwise you will need a double filament socket.

The fact that I am opinionated does not presuppose that I am wrong......

You will need three wires, one for the tail lights, one for the right signal/brake light and the third for the left signal/brake light. Of course, you will also need a ground wire.

You cannot do it with a single filament bulb, either you need two bulbs or a dual filament on each side of the trailer rear end.
