The new BMW M4 CSL boasts a unique feature in the form of motorsport yellow daytime running lights, which draw inspiration from the appearance of GT racing cars. The BMW Laserlight headlights that house these yellow running lights add a touch of the racetrack to the front of the car. The angular daytime running lights illuminate in yellow instead of white during the welcome sequence upon unlocking the doors, as well as when the low and high-beam headlights are turned on.

The HM WRGB DRLs offer seamless color changes through the integrated iOS and Google Play store applications. Our DRLs are WRGB (not to be confused with RGB), allowing you to switch back to white for that authentic 'OEM-look' at any time. Installation requires some wiring; therefore, we highly recommend professional installation. Everything you need for installation is included in the kit. This kit is fully reversible, permanent modifications are not required for installation.

Current photos are placeholders, actual board shapes will vary slightly.

- Some wiring is required. Wiring instructions are included. The red and white wire extending from the Bluetooth controller can be combined. This will start the Bluetooth controller anytime the car is on. Thermal adhesive is not included. Installation takes roughly 2 hours. We also offer the CSL Yellow DRL, which requires no wiring. You can find them here.

- Set includes low beam and high beam LED boards for both driver and passenger side headlights.

- Basic wiring instructions are included, but we always recommend professional installation by an installer with prior wiring experience. DIY is not recommended for this mod.

- DRL can be changed to any color using the integrated Bluetooth-based mobile application. You will notice a slight decrease in overall DRL brightness. This will not affect your actual headlights. 

- The QR code to download the app can be found on the side of the WRGB controller's box. To use it, just scan the QR code with your mobile device, compatible with both iOS and Google Play devices.
