How to Add Lights to a Sweater

Why You Should Add Lights to Your Sweater

There are plenty of reasons to add lights to your sweater. For one, it’s a great way to show off your holiday spirit. Lights can also help you stand out from the crowd if you’re not feeling particularly festive. They’re also a great way to add some extra warmth to your outfit. And let’s be honest, who doesn’t love a good light show? No matter your reasons, adding lights to your sweater is a fun and easy way to spruce up your style.

Another great thing about lights is that they come in all sorts of shapes, sizes, and colors. You can choose from mini, LED, or battery-operated lights. And if you’re feeling really creative, you can even make your own light show with string lights. Finally, lights are relatively inexpensive, so you can add them to as many sweaters as you want without breaking the bank.

Step by Step How to Add Lights to a Sweater:

1. Gather Your Supplies

The first step is to gather your supplies. You’ll need a sweater, lights, batteries, needle, and thread. You can find lights at your local craft store or online. As for batteries, we recommend using AA or AAA batteries. They’re inexpensive and easy to find. If you’re using LED lights, you may need a different type of battery.

2. Choose the Right Lights

Now it’s time to choose the right lights for your sweater. There are two things you’ll need to consider: the type of light and the size of the light. For the type of light, you can choose from mini, LED, or battery-operated lights. Mini lights are the smallest and most versatile option. They’re perfect for adding a little bit of light to your sweater without being too over the top.

LED lights are slightly larger than mini lights but are more energy-efficient. And battery-operated lights are the largest option, but they’re the easiest to use. As for the size of the light, you’ll need to decide how big or small you want your light show to be. If you’re just looking to add a little bit of light, we recommend using mini lights. But if you want to go all out, you can use up to 100 battery-operated lights.

Attach the Lights to  Your Sweater

3. Attach the Lights to Your Sweater

Now it’s time to attach the lights to your sweater. Start by threading a needle with about two feet of thread. Then, tie a knot at the end of the thread. Next, poke the needle through the back of the sweater, about an inch below the neckline. Now, thread the lights through the needle. Start with the light’s positive ( + ) end, and then thread the negative ( – ) end through. Repeat this process until all of the lights are attached to the sweater. Finally, tie off the thread and cut off any excess. If you’re using battery-operated lights, you’ll need to attach the batteries now.

4. Choose the Right Batteries

Now that the lights are attached to the sweater, it’s time to choose the right batteries. We recommend using AA or AAA batteries if you’re using mini lights. If you’re using LED lights, you may need a different type of battery. And if you’re using battery-operated lights, you’ll need to use the batteries that came with the lights.

5. Hide the Batteries

Now that you’ve chosen the right batteries, it’s time to hide them. The last thing you want is for your batteries to be visible. You can use various methods to hide the batteries, such as taping them inside the sweater or using a battery case. If you’re using a battery case, make sure to attach it securely to the sweater, so it doesn’t fall off.

6. Add an on/off Switch

We recommend adding an on/off switch if you’re using battery-operated lights. This will make it easy to turn the lights on and off and will help preserve battery life. Adding an on/off switch is a relatively simple process. First, identify the positive and negative wires on your lights.

Then, use a small piece of electrical tape to attach the positive wire to the on/off switch. Finally, use another piece of electrical tape to attach the negative wire to the on/off switch. Make sure that the connections are secure, and then test the lights to see if they’re working properly.

7. Add a Timer

A timer is a great way to conserve battery life. You can set the timer so that the lights only come on when it’s dark outside, or you can set it so that the lights turn off after a certain amount of time. To add a timer, first, find a small battery-operated timer. You can usually find these at your local hardware store.

Next, cut a small hole in the back of your sweater, near the bottom. Then, insert the timer into the hole and sew it in place. Finally, set the timer according to the instructions. Now, your lights will only come on when you want them to!

8. Test the Lights

Before you wear your sweater, it’s important to test the lights. This will help ensure that everything is working properly and that there are no loose connections. To test the lights, first, turn on the power source. Then, gently press each light into the sweater to make sure it’s securely in place. Finally, turn on the switch to see if the lights come on. If they don’t, check the connections and try again. If the lights still don’t work, you may need to replace the batteries.

9. Wear Your Sweater

Now that your sweater is all set, it’s time to wear it! Be sure to turn off the lights when you’re not wearing the sweater to conserve battery life. And, if you’re using battery-operated lights, be sure to keep an extra set of batteries on hand, just in case.

Use a Small Piece of  Electrical Tape

How Much Does It Cost to Add Lights to a Sweater?

The cost of adding lights to a sweater will vary depending on the type and number of lights you use. Mini lights are the most inexpensive option, and they can be found for as little as $0.50 per light. LED lights are more expensive, but they’re also more durable and longer lasting. Finally, battery-operated lights are the most expensive option but also the most convenient.

Battery-operated lights will cost you about $6 per light, and you’ll also need to purchase batteries. LED lights will cost you about $1 per light. And mini lights will cost you about $0.50 per light. So, the total cost of adding lights to a sweater will depend on the type of lights you use.

Tips and Warnings on How to Add Lights to a Sweater


  1. Choose a sweater that is made of a light knit fabric. The lights will not show through if the sweater is too thick.
  2. If you want the lights to twinkle, look for string lights that are specifically designed for that purpose.
  3. You can also use regular Christmas lights, but they will not twinkle.
  4. Choose a string of lights that is the same color as the sweater or white lights.
  5. If you want the lights to be removable, sew on velcro strips to the inside of the sweater so that you can easily take them off when you need to.
  6. Be sure to test the lights before you sew them onto the sweater to make sure that they work.
  7. Sew the lights onto the sweater using a needle and thread. Start at the bottom of the sweater and work your way up.


  1. Do not put too many lights on the sweater, or it will be too heavy and uncomfortable to wear.
  2. Be careful not to sew the lights too close together, or they may short circuit.
  3. Always unplug the lights before you remove them from the sweater.
  4. Never leave the lights on unattended.
  5. Do not wear a sweater while sleeping.

Frequently Asked Questions

Can You Wash a Sweater With Lights?

No, you cannot wash a sweater with lights. This is because the intense light output from the lights can cause irreparable damage to the fabric. If you absolutely must wash your sweater with lights, try using a low-light setting or washing it in cold water first to reduce the intensity of the light.

Can I Stick Led Lights to Fabric?

Yes! You can stick LED lights to fabric with a little bit of adhesive and some fabric tape. Here’s how to do it:

  1. Start by tracing the outline of your LED light onto the fabric with a pencil. Make sure the light is facing in the correct direction.
  2. Next, cut out the shape of the LED light with a pair of scissors. Try to make sure the outline of the light is still visible on the fabric.
  3. Apply a thin layer of adhesive to one side of the LED light, and place it onto the desired area on your fabric. Make sure that the light is facing in the correct direction.
  4. Once the adhesive has dried, use some fabric tape to secure the light in place. You can also adjust the position of the light by moving it around until you’re happy with how it looks.

Do Led String Lights Get Hot?

Yes, LED string lights do get hot. This is because LEDs are warm to the touch and emit heat as they generate light. In order to keep your strings from getting too hot, it’s best practice to position them properly and use fanning techniques when needed. Additionally, make sure that you’re using high-quality LEDs that have a good energy efficiency rating in order to reduce heating costs.

Do Fairy Lights Burn Out?

Fairy Lights don’t actually burn out, they just become less bright over time. This is because the light bulbs inside them use a technology called electropollution. Electropollution is when an electric current passes through a gas, and as the electrons in the gas are excited, they release their energy in the form of photons (light).

As fairy lights age, their light becomes weak due to this process. In most cases, however, these lights can still be used for decorative purposes without issue.


So there you have everything you need to know about how to add lights to a sweater. Follow these tips, and you’ll be sure to have a festive and stylish sweater that will be the talk of any party. Just be sure to take some precautions to avoid any accidents. If you have any questions, feel free to leave a comment below. Have fun and stay safe!
