Creating your own LEGO® LED lights is a great way to get creative and learn more about electronics. By following the steps outlined below, you can create your own customized LEGO® LED lights that can be used for all sorts of projects, from lighting up a diorama or creating unique wall art. With just a few simple materials, you’ll be able to construct your own LEGO® LED lights in no time.

Why Should I use LEGO® LED Lights?

LEGO LED lights are a great way to bring life and color to your projects. The lights come in a wide variety of shapes, sizes, and colors; allowing you to create unique designs that will stand out from the crowd. They’re also incredibly versatile. You can easily customize them with resistors and other components for more complex projects. Plus, they’re energy-efficient, meaning you won’t have to worry about running up your electricity bill.

Materials needed for a DIY LEGO® Lights KIT

1. Powering accessories

You’ll need some sort of battery or power adapter to make your LEGO® LED lights work. Common options include a 9V battery clip, AAA batteries, AA batteries, and a USB power supply.

2. LEDs

There are many different types of LEDs available for use in your project. The most common type is an SMD 5050

3. Battery Pack

Depending on the type of power supply you’re using, you may need a battery pack to hold your batteries.

4. Cables/Wire

You’ll also need some sort of connecting wire or cables to connect your LEDs and power supply together.

5. Resistors

To ensure that your LED lights aren’t too bright, it’s important to use resistors. The resistance determines how much current is allowed to pass through the LEDs.

6. Soldering Iron

You’ll need a soldering iron and some solder in order to make your connections between components.

7. Expansion Boards

To make it easier to connect multiple LEDs together, you may want to use an expansion board. This is a simple circuit board that connects all the components together for easy wiring and soldering.

How Do I Make LEGO® LED Light Kit?

To get started, you’ll need a few basic materials. First, you’ll need some LEGO® bricks. You can find these at any toy store or online. Then, you’ll need to pick up some LED lights. These come in various colors and sizes; so make sure to choose ones that fit the project you have in mind. Finally, grab some resistors—these will help regulate the current flowing through your circuit and keep it from overloading.

Once you have all of your components gathered up, it’s time to start building! Begin by connecting your resistors directly to your LEDs. This is done by soldering the leads together with a soldering iron. Once they’re connected, it’s time to attach the LEDs to the LEGO® bricks. You can do this by using hot glue or epoxy.

Finally, connect all of your components together in a circuit and test it out! If everything is working correctly, you should see your LED lights light up when they get power. Congratulations on creating your own custom LEGO® LED light kit!

Using Your LEGO® LED Lights

Now that you’ve constructed your own LEGO® LED lights, you can begin using them for all sorts of projects. Whether you want to create a unique wall art piece or light up a diorama; the possibilities are endless! With some imagination and creativity, there’s no limit to what you can create.

Now that you know how to make your own LEGO® LED lights, it’s time to get creative! Have fun and get inspired. Who knows, maybe you’ll come up with something amazing! Good luck!

Hey, I am Matthew Mitchell and I am an AFOL from the UK. I have been fascinated by LEGO® since I was a child. My two children are in love with LEGO® and it's because of them that my interest continued to grow, this is how I fell in to the rabbit hole of MOCs (my own creation). 

With every new MOC I saw I became just a bit more addicted to the endless possibilities that LEGO® offers. This led me to creating Belle-Ve Bricks, a platform where talented designers can share their work with the world.

And where we can create together with you, custom models.
