But my tail light won't light up if the connectors are plugged in one way, but will work if plugged the other way. Surely if the output was AC it wouldn't matter?

I've understood that even with AC the electricity basically comes from one of the wires and in a LED it can only get through in one direction, so if it's on the wrong connerctor, it won't light up.
