Give your Audi A4 or S4 a distinctive new daytime running light appearance with replacement LED DRL boards developed for compatible original Audi headlights. Choose a permanently illuminated Red configuration or select RGB+W for app-controlled colors, a dedicated white tone and extensive lighting customization.
Choose Your DRL Style
Select the fixed Red version for a bold lighting signature or choose RGB+W for adjustable colors and smartphone-controlled customization.
Red
A deep red lighting signature that gives the front of your Audi a bold, aggressive and unmistakable appearance.
RGB+W
Choose from a broad color spectrum, activate a dedicated white tone and personalize the daytime running lights through the compatible smartphone app.
Fixed Red Illumination
The Red boards provide a permanently selected color whenever the daytime running lights are active. No smartphone app or Bluetooth color controller is required.
Smartphone-Controlled Customization
The RGB+W version uses an additional Bluetooth controller for communication with the compatible smartphone app. The app can be accessed by scanning the QR code supplied with the controller.
In addition to opening the headlights and replacing the original DRL boards, the included Bluetooth controller must be mounted and electrically connected separately.
Compatible Audi Models
This product is intended for compatible Audi A4 and Audi S4 models within the listed 2013–2015 product range. Compatibility depends on the original headlight configuration installed in the vehicle.
Audi A4 2013–2015
Intended for compatible Audi A4 models equipped with the original headlight design shown in the corresponding product images.
Audi S4 2013–2015
Intended for compatible Audi S4 models equipped with the corresponding original headlight design shown in the product images.
Audi A4 and S4 models can be equipped with different internal headlight configurations. Please ensure that your car headlights are the same as the ones shown in the product image(s) before ordering.
Important Installation Requirements
The original DRL boards are located inside the sealed headlight assemblies. Installation therefore requires the headlights to be removed and opened before the replacement boards can be installed.
Headlight Lens Removal
The headlight lens must be carefully separated from the housing to access and replace the internal original DRL boards.
Professional Installation
Professional installation is strongly recommended because the headlights must be opened, correctly reassembled and properly resealed after the replacement boards have been installed.
After installation, the headlight lens and housing must be carefully reassembled and resealed to help protect the internal components from moisture and contamination.
