Stuart,
Let me clarify. I have two lamps/bulbs on each side, single filaments. One wire/bulb on each side works the turn signals and then one bulb/wire on drivers side runs the tail lamp and the passenger side light runs the stop light. Can the turn signal be wired together with the stop lamp light(each side)if I put a double filament socket with two wires? Sorry for the confusion... Been working on finshing up a bunch of things on the truck..long day.

John
