1. Introducció
This manual provides detailed instructions for the installation and operation of the Diode Dynamics RGBW DRL Boards for 2019 and newer Ram 1500 Laramie, Rebel, and Big Horn models equipped with the factory LED package. These replacement LED boards enhance your vehicle's daytime running lights (DRLs) by adding full multicolor functionality while retaining the option for a pure, bright white output.
The RGBW design incorporates an additional dedicated white LED chip alongside the red, green, and blue chips. This allows for a more uniform and brighter white light compared to mixing RGB colors, ensuring a clean, factory-like appearance when desired. The boards are engineered using OEM data for precise fitment and integrate seamlessly with your vehicle's existing headlight optics.

6. Configuració i instal·lació
Installation of the Diode Dynamics RGBW DRL Boards involves disassembling the factory headlights, replacing the original DRL boards, and wiring the new components. It is recommended that this installation be performed by an experienced technician or individual with advanced automotive electrical knowledge.
6.1. General Procedure Overview
- Headlight Removal: Carefully remove the vehicle's headlights from the front fascia.
- Headlight Disassembly: Open the headlight housing to access the factory DRL boards. This typically involves heating the headlight to soften the sealant.
- Substitució de la placa: Remove the original DRL boards. The Diode Dynamics RGBW boards are CAD-designed for a perfect fit and will align directly with the factory mounting points.
- Headlight Reassembly: Seal the headlight housing securely to prevent moisture intrusion.
- Connexions de cablejat: Connect the included waterproof drivers, RGBW extension wire, Solid-State Relay Harness, and Battery Input Wire according to the detailed wiring diagram provided in the physical installation guide.
- Factory Signal Integration: The Solid-State Relay Harness is designed to draw power from the battery while utilizing your factory parking light and sidemarker signals to activate the DRLs. This ensures proper operation without triggering vehicle computer errors.
- Prova: Before fully reassembling the vehicle, test the functionality of the DRLs with your RGBW controller.
- Final Reassembly: Reinstall the headlights and any removed fascia components.
6.2. Consideracions importants
- The included T-taps are for connecting to the factory parking light and sidemarker signals. Refer to the specific wiring diagram for your vehicle model.
- The system is engineered to prevent electrical errors with the vehicle's computer by correctly managing power draw.
- Ensure all connections are secure and waterproof to maintain product longevity and prevent electrical issues.
7. Funcionament
Operation of the RGBW DRL Boards requires a compatible RGBW controller (sold separately). The controller allows you to select various colors and effects for your DRLs.
7.1. Selecció de colors
Using your RGBW controller, you can:
- Select from a wide spectrum of colors by adjusting the Red, Green, and Blue channels.
- Activate the dedicated white chip independently for a pure, bright white DRL output. This is recommended for everyday driving to maintain a factory appearance.
- Combine colors with the white chip for unique shades.
