🚗 Step-by-Step Installation
Step 1: Test Your DRL Boards
Before beginning the install:
Plug in your RGBW DRL boards with your controller to verify full functionality.
Confirm that colors change correctly, the app connects via Bluetooth, and the LEDs operate as expected.
Step 2: Prepare Your Vehicle
Park your vehicle on a level surface.
Turn the engine off and let the headlights cool down.
Turn the front wheels away from the side you're working on for easier access to the fender liner.
Step 3: Access the DRL Module
Locate the wheel well access panel directly behind the headlight.
Use the appropriate screwdriver to remove the screws and take off the panel.
You’ll now see the rear heat sink module of the headlight.
Step 4: Remove the Factory DRL Module
Carefully unplug any wiring or connectors from the heat sink.
Unscrew and remove the heat sink module from the headlight housing.
Locate the factory DRL LED board mounted on the heat sink.
Step 5: Replace the DRL Boards
Unfasten the factory LED board from the heat sink using the correct tools.
Note the orientation of the original board before removal.
Mount the new RGBW DRL board in the same position.
Secure it using the included screws or clips and reconnect any wiring as needed.
Step 6: Reassemble the Module
Reconnect the wiring harnesses to the new LED board.
Reinstall the heat sink module back into the headlight housing.
Make sure everything is securely fastened.
Step 7: Reinstall the Wheel Well Cover
Align the fender liner access panel and fasten it back into place.
Ensure all screws are secure and the panel sits flush.
