^^thats the lights......and thats the plug^^^

leaveing 2 wires, grab a 9v battery
and try one end of the wire on the + and one on the -, if it dont light up try the other way round, it may only light them up dim with one 9v so perhaps you could chain a couple together, this could honestly be done with no soldering, just electrical tape and wire trims
