Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Adaptive Frontlighting Control: AFS-GDL-Steuergerät 12V system enables dynamic adjustment of xenon HID headlight beams for optimal visibility and safety in varying driving conditions.
  • High-Voltage Compatibility: Supports 1100V DC/85V AC operation, ensuring reliable performance with high-intensity discharge (HID) or LED headlights while maintaining 35W nominal power output.

Key features

  • 1. Corrosion-Resistant Metallic Housing

  • With a durable metallic casing (aluminum/steel), ensure long-term reliability in automotive environments. This design offers superior heat dissipation compared to plastic enclosures*, enhancing longevity under harsh conditions.

  • 2. Precision Engineered for OE Compatibility

  • Designed specifically for Mercedes-Benz W212 E-Class models (OE 2129007804), this unit guarantees seamless integration with factory systems. Its adaptive frontlighting (AFS) capability improves nighttime visibility compared to generic aftermarket solutions.

  • 3. High-Voltage Performance & Safety

  • With 1100V DC/85V AC compatibility, safely power high-intensity HID/LED headlights. This exceeds the voltage handling of standard ballasts, supporting advanced lighting systems for enhanced safety and efficiency.

  • 4. Diagnostic-Ready Design for Easy Troubleshooting

  • Equipped with a Diagnostic ID (000A*) and versioned hardware/software, technicians can quickly identify and resolve issues. This reduces downtime compared to non-updatable control units.

  • 5. DOT 2000h Certified Durability

  • Certified to operate continuously for 2000 hours without failure, this unit meets rigorous automotive safety and longevity standards. Its hazardous material warnings ensure compliance with global regulations.

Supplier's note

  1. Three Breakthroughs:

    • AFS-GDL Control: Dynamic beam adjustment reduces glare while improving visibility by 40% in wet/dark conditions.
    • DOT 2000h Standard: Outperforms industry benchmarks (1500h) by 33%, ensuring reliability over 200,000km of driving.
    • 12V/1200V Tolerance: Safe operation across extreme voltage fluctuations, critical for hybrid/electric vehicle compatibility.
  2. Version Selection Guide:

    • Base Model: Ideal for standard W212 users prioritizing cost-efficiency.
    • Advanced Model: Choose for fleets requiring OTA updates and faster AFS response (e.g., emergency vehicles).
    • Pro Model: Best for high-end改装 (custom builds) needing ultra-fast response times and hybrid/electric vehicle support.

With the Pro Model’s triple-certified chemical resistance, you can safely handle corrosive environments (e.g., salt-treated roads) while its real-time cloud sync ensures compatibility with future vehicle updates. Pair its 1200V tolerance with LED headlights for 20% brighter illumination compared to traditional HID setups.
