If you need to visually inspect your Christmas lights to determine which are good and which need replacement, there are a few things to look for. First, look for discoloration, such as a dark spot or two on the inside of the glass. The spot is an indication of a burnt filament. Also, look for missing filaments, cracked bulb glass, and broken sockets.

The simplest way to put Christmas lights on any metal surface is by using a magnetic hook or clip. You can also purchase magnetic lights, which should easily stick to any magnetic surface. Keep in mind that not all metals are magnetic. In that case, you’ll need to use a different clip.

Yes, you can try removing and replacing each individual light bulb one at a time until you find the problem bulb—just be prepared for it to take a while. The bulb tester is worth the investment if you don’t have a lot of extra time to spare or need to test several strands of lights.

How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It’s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit.
