If you’re looking to upgrade your vehicle’s lighting, you may be considering LEDs. LED lights are more energy-efficient and longer-lasting than traditional bulbs, and they can give your car a unique look. However, installing LED lights can be tricky, especially in newer cars. In this guide, we’ll show you how to install led lights in a Scion tC 2015.

What You Will Need

In order to install LED lights in your Scion tC 2015, you will need the following:
-1 set of LED lights (of your choice)
-1 set of brackets (custom made or purchased)
-1 set of lighted bumper reflectors (optional)
-Wire cutters
-Drill and bits
-Double sided tape
-Electrical tape
-Zip ties

Tools Needed

In order to install LED lights in your Scion TC 2015, you will need the following tools:

– screwdriver
– garden shears
– wire strippers
– 6 inch section of 3/4 inch PVC pipe
– utility knife
– hammer
– 1/2 inch drill bit
– electric drill
– 3/8 inch drill bit
– soldering iron
– solder
– heat shrink tubing
– wire ties
(- small flathead screwdriver (for opening the headlight))

Step One: Preparing the Car

Before beginning the installation,wash the car and clean the areas where you will be working. This will help to prevent dirt and debris from getting into the car’s electrical system. Next, park the car in a well-lit area so that you can see what you are doing.

In order to access the areas where you will be working, you will need to remove some of the car’s interior panels. Start by removing the screws that hold the panel in place. Then, carefully pull the panel away from the car’s body. Repeat this process for all of the interior panels that you need to remove.

Once all of the interior panels have been removed, locate the car’s battery. Disconnect the negative terminal first, and then disconnect the positive terminal. This will prevent any shorts from occurring while you are working on the car’s electrical system.

Step Two: Installing the Lights

Installing LED lights in a Scion tC 2015 can be done in two steps. The first step is to remove the factory headlights. The second step is to install the new LED headlights.

To remove the factory headlights, open the hood and locate the headlight assembly. There are four screws that hold the headlight assembly in place. Remove these screws and pull the headlight assembly out of the vehicle.

To install the new LED headlights, insert the headlight assembly into the opening in the vehicle. Secure the headlight assembly in place with the four screws. Then, reconnect the electrical harness to the back of the headlight assembly.

Step Three: Connecting the Lights

Now that the new LED lights are in place, it’s time to connect them. Begin by gently pushing on the back of the light until it pops out. There are three wires protruding from the back of the light – a black one, a red one, and a white one. Identify the black wire, and twist it around the black wire coming from the car. Do the same for the red and white wires. Once all three wires are securely twisted together, push the light back into place.

Step Four: Testing the Lights

The last thing you want is to be driving around with your new LED lights and have them constantly flickering or going out. To avoid this, it’s important to test the lights before you install them.

1. Begin by disconnecting the negative battery terminal. This will ensure that there is no power going to the lights while you are testing them.

2. Once the negative battery terminal has been disconnected, connect one of the LED light bulbs to the power supply. Make sure that the connection is secure and that there is no chance of the bulb coming loose while you are testing it.

3.Now, turn on the power supply and observe the light bulb. It should illuminate without any issue. If it doesn’t, check the connection to make sure that it is secure. You may also want to check the bulb itself to see if there is anything obstructing it or preventing it from lighting up.

4. If the light bulb turns on without any issue, turn off the power supply and repeat this process for each of the remaining LED light bulbs.

5. Once you have tested all of the LED light bulbs, re-connect the negative battery terminal and turn on your car’s ignition switch. This will allow power to flow back into the lights so that you can test them one last time before you install them permanently


In conclusion, installing LED lights in a Scion tc 2015 can be easy and fun. It is important to follow the instructions carefully and to take your time when installing the lights. With a little patience and attention to detail, you can have your car looking great in no time.
