  • Phillips screwdriver
  • Flathead screwdriver
  • Heat gun or oven
  • Pliers
  • Butter knife or spatula
  • Drill with appropriate bits
  • Rubbing alcohol
  • Masking tape
  • Spray paint (gloss black)

Please note that safety should be your top priority during the installation process. Use caution when handling tools and heating elements, and consult professional assistance if needed.


Step 1: Removing and Disassembling the Headlights

  1. Start by removing the four screws holding each headlight in place. These screws are typically located at the corners of the headlights.

  2. Once the screws are removed, carefully slide the headlights out and disconnect any electrical connectors.

  3. Preheat the oven to 250 degrees Fahrenheit (120 degrees Celsius). Place the headlights on a baking sheet and put them in the oven for approximately 10-15 minutes. This step is necessary to soften the adhesive and facilitate easier disassembly.

  4. After heating, use a butter knife or spatula to pry open the headlight housing. Start by prying from one side and work your way around. Take your time to avoid damaging the plastic.

  5. Once the housing is open, remove any adhesive residue and clean the interior surfaces with adhesive remover and clean rags. This step ensures a clean and secure seal when reassembling the headlights.


Step 2: Installing the Demon Eye Kit

  1. Begin by preparing the demon eye kit. The kit should include wires, an LED driver, and the demon eyes themselves.

  2. Carefully position the demon eyes in the desired location within the headlight housing. Take note of the wiring connections and ensure they are accessible for future steps.

  3. Secure the demon eyes in place using the provided screws or adhesive, depending on the design of the kit.

  4. Run the wiring from the demon eyes to the LED driver, ensuring a neat and organized layout. Use wire connectors and heat shrink tubing to make secure and insulated connections.

  5. Connect the LED driver to the power source according to the provided wiring diagram. Double-check all connections to ensure they are correct and secure.


Step 3: Installing the LED Boards

  1. Take the LED boards and position them correctly within the headlight housing. Ensure they align properly with the existing mounting points.

  2. Secure the LED boards in place using the provided screws. Pay attention to the correct placement and alignment.

  3. Connect the wiring harness from the LED boards to the appropriate connectors on the headlight assembly. Refer to the provided wiring diagram for proper connections.

  4. Test the functionality of the LED boards and demon eye kit to ensure they are working correctly. Make any necessary adjustments or troubleshooting as needed.


Step 4: Reassembling and Sealing the Headlights

  1. Clean the lens and housing surfaces to remove any dirt, fingerprints, or residue.

  2. Apply silicone sealant along the edges of the headlight housing. Ensure complete coverage to create a watertight seal.

  3. Carefully reassemble the lens and housing, aligning them properly. Apply gentle pressure or use clamps to secure the housing together.

  4. Allow the silicone sealant to cure for the recommended time, typically around 40 minutes, before proceeding.

  5. Reinstall the headlights by reconnecting any electrical connectors and securing them with the previously removed screws.

  6. Attach the plastic covers or clips to secure the headlights in place.

  7. Clean the exterior surfaces of the headlights to remove any smudges or marks.



Installing The RGB+W Version Of DRL Boards

If you're intrigued by the prospect of adding a vibrant twist to your car, you might consider installing the RGB+W version of the DRL boards. However, keep in mind that the RGB+W version may not be as bright as the OEM, and the installation process includes a few more steps due to extra wiring. Also, remember that this RGB+W version's control doesn't rely on the in-car switch but is managed through an app, and it activates when the car is on or off, not with your welcome lights. 


Step 1: Installing The RGB+W Boards

The initial steps for installing the RGB+W boards are the same as those for the single color version. Once you've successfully installed the boards, you'll find there are extra wires to manage.


Step 2: Connecting To Switched Power

Next, you'll need to connect the harness and Bluetooth module to a switched power source. There's a switched power source available in the engine bay fuse box on the passenger side. However, using an add-a-fuse here won't allow you to replace the fuse box cover. If you're unwilling to leave the cover off or cut it, an alternative option is to run a positive wire to the trunk and use a switched power source from there.


Step 3: Managing The Harness And RGB+W Controller

Run the wiring harness from the boards to the RGB+W controller. The controller features a QR code on its back for you to download the required app to manage the RGB control.


Step 4: Managing The Wiring

The wire from the RGB+W boards gets pinched between the headlight housing and the foam gasket of the heat sink. This doesn't exert too much pressure and the foam gasket seals around the wiring to prevent water ingress.

As you go through this process, keep in mind the considerations mentioned above, as these will help you decide whether or not the RGB+W version is a good fit for you. Despite the extra steps and considerations, if you're an RGB person, this addition can add a fun and vibrant touch to your car.
