In this project, you’ll learn how to make custom LED tail lights for cars. You’ll need a few materials and tools to get started, but once you have everything, the project is straightforward and should only take a few hours.

Custom LED tail lights are a great way to add style and personality to your car, and they can also improve your visibility on the road. If you’re not satisfied with the look of your car’s stock tail lights, or if you want to add something extra to make your car stand out, this project is for you!

Tools and Materials Needed

In order to make your own LED tail lights, you will need a few tools and materials. First, you will need a drill and drill bit. Next, you will need a Dremel tool with a cutting blade attachment. You will also need a soldering iron and solder. Finally, you will need a length of thin gauge wire and some heat shrink tubing.

With these tools and materials, you will be able to create custom LED tail lights for your car. First, you will need to drill a hole in the back of your car’s taillight housing. Next, use the Dremel tool to cut a slot in the housing for the wire to go through. Then, solder the wire to the positive and negative terminals on the LED bulbs. Finally, use the heat shrink tubing to protect the connections.

Step One: Preparing the Tail Light Housing

The first step in making your own custom LED tail lights is to prepare the tail light housing. You will need to remove the old bulbs and any other hardware that is attached to the housing. Once this is done, you will need to clean the housing thoroughly. Any dirt or debris that is left on the housing can cause your new LEDs to malfunction.

Step Two: Cutting and Drilling the Lens

Now that you have your new lens, it’s time to personalize it. You will need to cut and drill the lens to fit your car.

First, use a marker to outline the area you want to cut out. Then, use a jigsaw or rotary tool to cut out the design.

Next, use a drill bit to make two holes in the lens. These holes will be used to attach the lens to your car.

Now that your lens is cut and drilled, it’s time to move on to the next step!

Step Three: Applying the led lights

Now that the channels are cut and the backings are in place, it’s time to apply the LED lights. You’ll want to start by striping about a half inch of the ends of the wires. Once that’s done, take your LEDs and insert them into the channels so that the positive and negative wires are on opposite sides. Make sure that the flat side of the LED is facing up, otherwise they won’t work properly.

After the LEDs are all in place, it’s time to solder them into place. You’ll want to start by soldering the positive wire of each LED to the positive wire of the next LED in line. Once that’s done, you can move on to soldering the negative wire of each LED to the negative wire of he next LED down the line. Continue doing this until all of your LEDs are soldered into place.

Once all of your LEDs are in place, you can test them by connecting them to a power source and seeing if they light up. If they don’t light up, check your connections to make sure that they’re all secure. Once you’ve confirmed that everything is hooked up correctly, you can proceed to step four.

Step Four: Wiring the Lights

Now that you have your new LED tail lights, it’s time to wire them up! This process is actually quite simple, and there are a few different ways you can do it. We’ll go over the two most common methods below.

If you’re not comfortable with electrical work, we recommend taking your car to a professional to have them wire up your new LED tail lights. This is the safest option and will ensure that your tail lights are installed correctly.

The first method is to use a wiring harness adapter. These adapters are designed to make installing LED tail lights into cars with standard incandescent bulbs easy. Simply plug the adapter into your car’s existing tail light wiring harness and then plug your LED tail lights into the adapter. The adapter will take care of the rest, providing power to your new tails from the brake light, turn signal, and running light circuits in your car.

If you don’t want to use an adapter, or if your car doesn’t have a standard incandescent bulb taillight wiring harness, you can wire the lights directly into your car using solderless connectors. This method is a bit more complicated, but it can be done without any specialized tools or knowledge. Just follow the instructions below carefully and you should be able to get your new LEDs wired up in no time!

Step Five: Finishing Up

The final step is to add a wire to the positive lead of each LED and connect it to your car’s positive tail light wire. Once you have done this, screw the lens back on and put the light back in place. Test it out to make sure it’s working before you go on your way!


In conclusion, making custom LED tail lights for cars can be done relatively easily, as long as you have the right tools and materials. With a little patience and attention to detail, you can create a unique look for your car that will really make it stand out from the rest.
