How To Open And Modify Car Headlights For DRL LED Board Replacement

EXL Design - DRL Board Replacement Guide

At EXL Design, we understand the desire to customize and enhance your car headlights. Replacing the Daytime Running Lights (DRL) boards is a popular modification that improves both aesthetics and functionality. This guide provides a step-by-step process for opening and modifying car headlights (removing the lens from the housing) to facilitate DRL board replacement.

If you were linked here from one of our products, this installation applies to your vehicle. While we do not have detailed instructions for every model, this guide ensures you have a solid understanding of the DRL board conversion process.

Note: If your DRL boards require a headlight opening for installation, this guide will assist in safely removing the lens from the housing. If you are unsure or uncomfortable with the process, we recommend seeking professional help or referring to instructional videos.

Step-By-Step Guide

Step 1: Preparing for the Modification

Before starting, gather the following tools and materials:

  • Heat-resistant gloves – Protects hands from heat.

  • Milwaukee tools or suitable screwdrivers – Removes screws securing the lens and components.

  • Oven or heat gun – Softens adhesive for headlight opening.

  • Butyl headlamp sealant – Ensures proper resealing post-modification.

  • Clean work surface – Keeps removed components organized.

Step 2: Preheating the Oven

If using an oven, follow these steps:

  1. Set the oven to 220°F (104°C) to avoid excessive heat.

  2. Allow the oven to preheat while preparing the headlights.

Step 3: Removing the Lens Screws

  1. Locate and remove all screws securing the lens.

  2. Use the appropriate screwdriver or Milwaukee tool.

  3. Organize screws for easy reassembly.

Step 4: Softening the Adhesive

For safe separation of the lens from the housing:

  1. Place the headlight on a heat-resistant surface inside the preheated oven.

  2. Ensure headlights do not touch metal surfaces.

  3. Let them warm for a few minutes until the adhesive softens.

  4. Use heat-resistant gloves to remove the headlights.

Step 5: Opening the Headlights

  1. Identify tabs holding the lens in place and bend them gently.

  2. Apply even pressure to push the lens forward, creating a gap.

  3. Pull the lens towards yourself carefully.

  4. Avoid using prying tools that may damage the housing.

Step 6: Modifying the DRL Boards

  1. Access the DRL boards.

  2. Follow the manufacturer's instructions for removal and installation.

  3. Handle the DRL boards carefully to avoid damaging components.

Step 7: Resealing the Headlights

  1. Remove any excess glue or debris from the lens.

  2. Apply butyl headlamp sealant around the perimeter of the lens.

  3. Align the lens correctly with the housing.

  4. Apply even pressure along the edges for a secure seal.

Step 8: Reassembling the Headlights

  1. Reinsert and tighten all screws securely.

  2. Check for proper alignment and fit.

  3. Clean the headlight exterior to remove fingerprints or smudges.

Installing the RGB Version of DRL Boards

If you are installing the RGB DRL boards, note the following:

  • The RGB version may not be as bright as OEM DRL.

  • The control is app-based, not managed via the in-car switch.

  • The RGB lights activate when the car is on or off, not with welcome lights.

Step 1: Installing the RGB Boards

  • Follow the same initial steps as the standard DRL board installation.

  • Manage additional RGB wiring carefully.

Step 2: Connecting to Switched Power

  • Locate a switched power source in the engine bay fuse box (passenger side).

  • Using an add-a-fuse here may prevent reinstalling the fuse box cover.

  • Alternatively, run a positive wire to the trunk and use a switched power source.

Step 3: Managing the Harness and RGB Controller

  • Run the wiring harness from the boards to the RGB controller.

  • Use the QR code on the controller to download the app for RGB control.

Step 4: Managing the Wiring

  • Route the RGB board wires between the headlight housing and the foam gasket.

  • The foam gasket seals around the wiring to prevent water ingress.

If you love RGB customization, this addition can provide a vibrant, unique touch to your vehicle.

Conclusion

By following this guide, you can achieve professional results while maintaining headlight functionality. Work carefully, use the right tools, and reseal properly to prevent damage.
