A conduction tester is a device with a bulb that can be used to determine whether an object is a good conductor or not.
The conduction tester is connected with the object in question, and electricity is made to pass through it. If the bulb starts glowing, it means that the electricity has managed to pass through the object, which means the object is a good conductor of electricity. If the bulb doesn't glow, the object is a bad conductor since it didn't let any electricity through.
So if the bulb started glowing when the object was connected to the conduction tester, it means that the object is a good conductor.
