Step 4Feed wires
Feed three wires about 18 to 24 inches long through the hole at the end of the flashlight. Make them different colors like I did and attach alligator clips to the ends. You can also use test lead wires with alligator clips already attached. Just cut one end off. You can find test leads with alligator clips at Radio Shack.
Solder a washer or copper disc (like mine) on the Cathode clip. This will be the negative end and will be shoved down the barrow of the flashlight against the spring.
Solder the other two wires to the contact ring at the bulb head. These wires will be the positive Gate and Anode clips
