If you find one, open it and inspect the very small fuses inside the plug. There should be two. If one or both of the fuses look black or cloudy, or if you can see that the wire through the fuse has burned in two, you need to replace the ones that look bad.

Three-amp, five-amp, and seven-amp fuses are common sizes. Unlike the regular lights and receptacles in your house, light strings, especially older ones, are often constructed with the light bulbs wired in series. This means that the power goes through each light bulb to get to the next one.

Slide this door open, pry out the small glass fuse and examine it closely. Some light strings may have two fuses; examine them both.

Here, it can be quite time-consuming to replace individual bulbs until you find the culprit causing the problem. There are different types of testers available, including "touchless" models that you simply hold close to each individual bulb to identify if it is bad.

With other tools, you remove individual bulbs and slide the plug portion into a small socket on the tool to test it. If none of the individual bulbs are faulty but the light string still refuses to light up, there is a chance the shunt wires in the light string are faulty. When working correctly, there is a wire shunt in the string that bypasses each of the individual light bulb sockets.

This is designed so that power continues to flow when an individual bulb is burned out. But if the shunt wire itself is faulty, the light string will fail to operate correctly. The Lightkeeper Pro is a trigger-operated tool that sends a pulse of current through the light string to identify the faulty light bulb and repair the shunt. The tool comes in a kit form that includes extra light bulbs, a continuity tester, and even a battery tester for testing various batteries.
