Take a piece of twin cable and bare the ends.
Using crocodile clips, connect one end of one wire to the positive side of a battery and the other end to the solder at the bottom of the little bulb.
The other wire, connect one end to the negative side of the battery and its other end to the brass case of the bulb.
The bulb will light up.
