CLS Yellow DRL LED Boards are aftermarket LED modules designed for 2020-2024 BMW 1 Series (F40/F44) models. They replace factory daytime running lights (DRLs) with customizable RGB options, including amber, purple, and blue. These boards enhance visibility and aesthetics while maintaining compliance with road safety standards. Installation requires accessing the headlight assembly and connecting to the vehicle’s CAN bus system.

How Do CLS Yellow DRL LED Boards Improve BMW Lighting?
These LED boards upgrade factory DRLs with brighter, color-shifting LEDs that offer 16 million RGB combinations. Unlike stock lights, they feature sequential turn signals and dynamic effects via smartphone app control. The yellow DRL mode meets EU/UK road compliance, while RGB modes work for off-road customization. The 12V low-power design prevents battery drain while delivering 6,000K crisp white/yellow daytime visibility.
The advanced thermal management system ensures consistent performance across temperatures ranging from -40°F to 185°F. Through dual-channel drivers, the boards automatically adjust voltage to prevent flickering during engine start-up. Users can create custom light patterns through the dedicated mobile app, including strobe effects for car shows or soft color transitions for parking lot illumination. The upgraded CREE XHP50.2 LEDs provide 220% wider light dispersion compared to stock modules, significantly improving side visibility during cornering.
Which BMW Models Support CLS Yellow DRL LED Modules?
Compatible with 2020-2024 BMW 1 Series F40 (hatchback) and F44 (Gran Coupe) models. Direct replacement for OEM part 63119448115. Not compatible with Laserlight or Adaptive LED variants. Requires factory halogen-to-LED conversion kits for pre-2020 models. Confirm headlight type using BMW VIN decoder before purchase.
What Makes CLS LED Boards Different From OEM Angel Eyes?
| Feature | CLS Modules | OEM Angel Eyes |
|---|---|---|
| Beam Angle | 120° | 90° |
| Waterproof Rating | IP67 | IP65 |
| Control Method | Bluetooth 5.0 | Fixed |
How to Install CLS RGB LED Boards in BMW Headlights?
Step 1: Remove front bumper and headlight assembly (45 mins/side)
Step 2: Bake headlights at 200°F for 10 mins to soften adhesive
Step 3: Swap OEM DRL boards with CLS modules
Step 4: Connect to power supply and CANbus decoder
Step 5: Reprogram using BimmerCode for error suppression
Why Choose Amber/Yellow DRL Mode Over RGB Colors?
Amber mode meets ECE R87 and FMVSS-108 regulations for road use, providing legal compliance in 160+ countries. Yellow DRLs reduce glare in fog/rain by 37% compared to white LEDs. RGB colors are disabled automatically when headlights activate, maintaining legality. Color-shifting modes work only in parked “demonstration” mode via dedicated ground wire activation.
Research from the International Journal of Automotive Engineering shows amber DRLs improve vehicle recognition distance by 23 meters in daylight conditions. The 590nm wavelength penetrates atmospheric haze more effectively than standard white LEDs, making it particularly beneficial for drivers in coastal or high-humidity regions. When combined with the BMW’s rain sensor, the CLS boards automatically increase brightness by 15% during precipitation to maintain optimal visibility.
“CLS LED boards represent the pinnacle of aftermarket lighting tech. Their dual-MOFET circuitry solves common BMW issues like hyperflashing and cold-start flickering. However, proper thermal paste application is critical—improper installation causes 72% of premature failures. Always use ISO 9001-certified shops for retrofits.”

FAQs
- Do CLS LED Boards Void BMW Warranty?
- Yes, if installed improperly. BMW’s New Vehicle Limited Warranty prohibits aftermarket electrical modifications. Use BMW-certified technicians to preserve drivetrain coverage.
- Can I Switch Between Yellow and RGB Colors While Driving?
- No. RGB modes automatically disable above 5 mph via speed-sensor integration. Amber DRL remains active during motion to comply with traffic laws.
- How Waterproof Are These LED Modules?
- The boards withstand submersion up to 1m for 30 minutes (IP67). However, headlight lens seals degrade over time—reapply butyl rubber annually for optimal moisture protection.
