Your Wesbar 102640 trailer light features a sealed capsule so the bulb itself cannot actually be replaced.
I recommend simply replacing the light assemblies with the Wesbar # 403026 and # 403076. These are the newer/current generation model lights to what you currently have.
On these light assemblies the white wire is for the ground, the brown is for the running light circuit and the yellow/green is the corresponding stop/tail circuit for either side of the trailer.
You'd need to test the wiring of your trailer with a circuit tester like part # PTW2993 to determine the function of the colors on your trailer and then wire accordingly.
