how to find dead christmas light bulb

In order to find a dead Christmas light bulb, you will need a multimeter. First, you will need to locate the dead bulb on the Christmas light string. Once you have found the dead bulb, you will need to remove the bulb from the socket. Then, you will need to turn on the multimeter and set it to the "ohm" setting. Finally, you will need to test the bulb to see if it is dead or not. If the multimeter reads 0 ohms, then the bulb is dead.
