You will need to use a circuit tester, item # PTW2993 if needed, to test the wires exiting the trailer to figure out the wiring configuration with the trailer hooked up to the truck and the running lights on.
You will probably find that you have taillight power on one of the green wires and no power on any of the other wires. In this case you would wire the two green wires to the power wire coming from the clearance light. You would then need to wire the two white wires coming from the trailer to the ground for the clearance light. Wiring this way allows the ground and taillight wiring to carry on to the next light inline on that side of the trailer.
It sounds to me like your lights are mounted in a location that requires a ground wire to be ran to the trailer frame. If so, lights with only a power wire will not work on your trailer without adding a ground wire to them and attaching it to the ground wires coming out of the trailer. We have two wire clearance lights available similar to those you referred to. The Oval Two-Bulb Trailer Clearance and Side Marker Light, 2 Wire - Amber, item # MC66AB, would be a good choice for this application.
