I have a kit of lights for the Lego Christmas Train. The kit comes with a battery box. So the lights are rated at around 4.5v. However this means that the train has to remain stationery (unless I bolt the additional battery box on board - unsightly). Fortunately the Christmas Train has a Lego engine and on board battery box. Can I connect the lights to the secondary connection that the Lego battery box has so that they are on as the the train moves. If so will the higher voltage kill the lights? If not is there a cable for achieving the connection. I welcome some advice.
