How to make a series test lamp
1. Cut the wire into two pieces making each one a meter long.👇

2. Now you have two pieces of wire. Fix the bulb holder using one end of the two pieces of wires and install a light bulb on to the holder.👇

3. You have other two ends of the wire free. Fix a two-pin plug on that free pairs of wires. It means you can light up the bulb if you put two-pin plug in a live two-pin socket.👇

4. Check the continuity of the test lamp by an Avometer; be sure that bulb turns on when the plug is inserted in a live two-pin socket.👇

5. Now, pull out the plug from the socket.👇

6. Finally, you need to slice one of the wires in the middle and remove insulation from each of the cut-ends for half an inch so that the bare copper is clearly visible.👇

7. Your test lamp is ready for experimental test. Always use a cap to cover the bare copper wire to avoid any accidental electrification.||
