“The 3748 Light unit for train is a attachment to the “My own train set” line, which would give the trains an option of having it able to have a light, to brighten up the tracks. The set only contains 4 pieces, of the major ones, there is the wire connector, and the light... More bulb. The only way to have it turn on, is to attach it to a 9 volt motor train.”
