Christmas is just around the corner, and nothing dims the festive spirit more than pulling out a string of broken lights. Maybe a section is dark, the whole strand flickers, or worse, they don't turn on at all. But before you toss out your lights or rush to buy new ones, it's worth checking for some common issues.
Many times, a single faulty bulb or a loose wire can be the culprit, and learning how to fix broken Christmas lights can save you both time and money during the busiest season. Read on as we walk you through the most common reasons Christmas lights fail and provide step-by-step instructions on how to get them glowing again.
Common Reasons for Christmas Light Failure
It's frustrating when your Christmas lights don't work, especially when you're excited to decorate! But the good news is, most light failures happen for a few common reasons that are easy to spot once you know what to look for. Here are the top culprits:
1. Burnt-Out Bulbs
If it's a smaller set of older incandescent lights, it's probably wired in series—meaning the electrical current flows through each bulb one by one to complete the circuit and light up the whole set. One bad bulb can take down the entire strand.
For larger sets, there are usually two or more circuits wired in parallel. If a single bulb burns out, it can cause its section of lights to go dark and the rest can still stay lit. Usually, just swapping out that one bad bulb will get the whole set or the dark section working again.
2. Blown Fuses
If your entire string of lights won't turn on, a blown fuse might be the problem. Christmas lights often contain small fuses located inside the plug. These fuses protect against power surges or overloads, but if one blows, the entire strand will stop working.
3. Loose or Broken Wires
Wiring problems can be tricky to spot but often occur if the lights have been bent, pinched, or tangled during storage. Frayed or damaged wires can interrupt the electrical flow, causing your lights to malfunction or not work at all.
4. Circuit Overload
If you've connected too many strands or devices to a single outlet, you could trip a breaker or blow a fuse. Christmas lights, especially older ones, can easily overload circuits if you don't follow safety guidelines.
5. Corrosion
Outdoor lights are exposed to weather elements like rain, snow, or extreme temperatures, which can lead to moisture buildup or corrosion, damaging the sockets and wires.
How to Fix Broken Christmas Lights
Now that you know the common reasons for Christmas light failure, it's time to learn how to fix them. Whether it's a burnt-out bulb or a broken fuse, follow these steps on how to repair broken Christmas lights to get them glowing again:
Testing and Replacing Burnt-Out Bulbs
If you're asking, "How do you repair Christmas tree lights?", the first thing to check is the bulbs. As we've learned, a single burnt-out bulb can cause a section or the entire string to stop working. Here's what to do:
- Identify the Bad Bulb:Begin by unplugging the lights and carefully examining each bulb for blackening or a broken filament. You can also use a bulb tester, which will help identify the faulty bulbs quickly. Just hold it over each bulb to see if it signals the faulty one.
- Replace the Burnt-Out Bulb:Once you've found the defective bulb, remove it by gently pulling it out of the socket and replace it with a new one of the same voltage. Make sure the replacement bulb is seated properly to ensure a strong connection.
- Test the Lights Again:Test the string by plugging it back in to see if the issue is resolved.
Checking and Replacing Fuses in Christmas Lights
If your entire strand of Christmas lights is not working and none of the bulbs seems broken, a blown fuse might be the problem. Christmas light fuses are typically located inside the plug, covered by a small compartment. To check the fuses:
- Locate the Fuse Compartment:Unplug the lights and look for a sliding cover or a small notch near the prongs of the plug.
- Open the Fuse Cover: Use your fingernail or a small flathead screwdriver to gently slide open the fuse compartment. You'll typically see two fuses inside, usually lined up next to each other.
- Inspect the Fuses:Examine each fuse to see if it's blown; a blackened or broken wire inside the fuse is a clear sign it needs to be replaced.
- Replace the Blown Fuse:Take one of the spare fuses (often included with your lights) and insert it into the compartment. Make sure it matches the voltage and amperage of the original fuse—this information is usually printed on the plug or packaging.
- Close the Fuse Cover and Test:Once the new fuse is in place, close the compartment securely and plug the lights back in. If the strand lights up, you're good to go!
Dealing with Wiring Issues and Circuit Overload
If your Christmas lights still aren't working after checking the bulbs and fuses, the issue could be with the wiring or an overloaded circuit. Damaged wires or too many connected strands can disrupt the flow of electricity and may even pose a safety hazard. Here's how to troubleshoot:
- Inspect the Wiring for Damage:Inspect the entire string of lights for any visible wire damage, loose connections, or exposed copper. If you find any exposed or damaged wires, it's safest to replace the strand altogether.
- Check for Loose Connections:Inspect where the light strand connects to the plug and any extensions. Sometimes, a poor connection between strands or to the power source can cause the lights to malfunction. Make sure each plug fits snugly and isn't loose or wobbly.
- Avoid Overloading Circuits:Plugging too many strands into a single outlet can trip your circuit breaker or blow a fuse. Follow the manufacturer's instructions—most traditional light sets recommend connecting no more than three strands together.
- Reset the Breaker If Needed:If your lights stopped working after plugging them in, you may have overloaded the circuit. Check your home's breaker box to see if a breaker has been tripped. If so, reset the breaker and reduce the number of light strands or decorations on that outlet.
Safety Tips for Storing and Handling Christmas Lights
Now that you know how to fix a strand of Christmas lights, it's equally important to store and handle them properly to prevent future damage and ensure safe usage. Follow these safety tips to keep your lights in good condition and reduce the risk of electrical hazards:
- Unplug Lights Before Handling: Always unplug your lights before attempting to fix, replace bulbs, or store them. This prevents electrical shocks and accidents during handling.
- Inspect for Damage Before Storing: Before putting your lights away, inspect them for any signs of frayed wires, broken bulbs, or damaged sockets. Dispose of any faulty lights instead of storing them for next season.
- Wrap Lights Properly: Avoid tangling by wrapping the lights around a piece of cardboard or a plastic spool. Neatly coiled lights are easier to handle and less likely to be damaged when stored.
- Store in a Dry, Cool Place: Moisture can cause corrosion and damage to the wiring, so store your Christmas lights in a dry, cool area. Avoid storing them in basements or garages.

FAQs
How to find a burned out bulb in Christmas lights?
To find a burned-out bulb, first unplug the lights and inspect each one for blackened or broken filaments. You can also use a bulb tester to quickly identify the faulty bulb. Once located, remove the dead bulb and replace it with one of the same type and voltage to restore the string.
How to fix Christmas lights when half are out?
If half of the string is out, the issue is likely with a single loose or faulty bulb. Unplug the lights and inspect each bulb. Tighten any loose ones, and if you spot a burnt bulb, often discolored or smoky, replace it with a new one of the same type and voltage rating. You can also use a bulb tester to find the faulty bulb quickly.
How to tell which bulb is out on a string of lights?
A bulb tester is the quickest way to identify a non-working bulb. Alternatively, you can visually inspect each bulb for any discoloration or broken filaments. Once you find the defective bulb, replace it to restore the entire string.
Is it safe to use Christmas lights with a broken bulb?
It's not safe to use Christmas lights with a broken bulb. Broken bulbs can expose the wiring and increase the risk of electrical shock or fire. Always replace damaged bulbs promptly to maintain safety and prevent further damage to the light string.
