Installation Process

Before we dive into the installation process, it's important to ensure the ignition is off and the battery is disconnected, to prevent electrical issues.

Step 1: Identify and Remove the DRL Module
  1. Locate the DRL modules. They are usually attached to the top or backside of the headlights. Unscrew the module using a T20 screwdriver. In some vehicles, you might need to remove the bumper, fender, or tires for better access.

Step 2: Detach the DRL Board from the Heat Sink
  1. Move the module to a suitable workspace. Identify the factory thermal glue between the heat sink and the DRL board. Using a utility blade, carefully separate the LED board from the aluminum heat sink.

Step 3: Clean the Heat Sink
  1. Once the board is removed, use a razor blade to scrape off the old thermal glue from the heat sink. Be careful not to scrape into the aluminum. Clean the heat sink with isopropyl alcohol, ensuring all remnants of the old glue are removed.

Step 4: Apply New Thermal Glue and Install the New DRL Boards
  1. Spread a line of thermal glue down the center of the new LED board's back. When placing the board on the heat sink, ensure the slots are centered and aligned with the tabs on the heat sink. Apply even pressure on the board to secure it, and use clamps to hold the boards in place.

Step 5: Let the Thermal Glue Dry
  1. Allow the thermal glue to dry for at least 1-2 hours before proceeding to the next step.

Step 6: Reassemble the DRL Modules
  1. Finally, remove the clamps, and begin the reassembly process. Connect the boards to their respective plugs, and then reinsert the module into the headlight housing. Tighten the module using the T20 Torx screws, but be mindful not to over-tighten, as this can cause damage to the plastic housing.

The single color or multicolor RGB version add a touch of uniqueness and emulate your vehicle for an unforgettable appearance. We hope you are happy with the results and that this guide has been helpful to you.

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
  1. The initial steps for installing the RGB+W boards are the same as those for the lemon yellow version. Once you've successfully installed the boards, you'll find there are extra wires to manage.
Step 2: Connecting To Switched Power
  1. 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
  1. 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
  1. 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.


With these steps, you can successfully upgrade your vehicle with our DRL boards.
