BMW Headlights, Headlight Lenses, & Headlight Parts for BMW 3 Series E90 (2006-2011)

Restore reliability to your E9x Headlights with ECS Tuning’s Premium Replacement Harness Kit.

Headlight electrical issues are a common headache for many E9x owners. Over time, the factory wiring inside Pre-LCI BMW E92 and E93 3 Series headlights, as well as all E9x M3 models equipped with factory Xenon adaptive lighting, tends to become brittle and crack. This well-known problem can lead to flickering lights, adaptive headlight malfunction warnings, or even internal shorts that cause costly damage. With genuine Xenon headlights becoming increasingly scarce, maintaining them has never been more important.

ECS Tuning offers a long-lasting solution with its Headlight Wiring Harness Repair Kit, engineered specifically to eliminate this failure point. Each harness is built from modern, heat-resistant materials and fitted with pre-terminated, OEM-style connectors for a clean, straightforward installation. The result is improved reliability and restored confidence in your lighting system.

Don’t wait until your lights fail or an adaptive headlight error appears. Replace your deteriorating factory harness with ECS Tuning’s upgraded repair kit and keep your lighting system performing as it should.

Installation & Support:

ECS Tuning provides a comprehensive installation guide that covers the entire process, from opening your OEM headlights to installing the new harness.

Over time, road grime, salt, and moisture take a toll on the factory rear leveling rod. The original equipment often corrodes, seizes, and eventually snaps—or worse, binds up and breaks your expensive headlight leveling sensor. With this issue in mind, ECS has engineered a heavy-duty, bulletproof solution designed to outlast the car it’s installed on.

Instead of brittle OE plastic that degrades and snaps over time, this rod is constructed from high-strength, flexible polyurethane. Paired with corrosion-resistant stainless steel ball studs, it guarantees smooth articulation and prevents the binding that destroys expensive sensors. Precision-manufactured for a perfect, bolt-on fit, this upgrade requires zero modifications to replace your fragile OEM unit.

This is a direct-fit replacement for Genuine BMW part number 37146752797, restoring proper suspension-to-sensor geometry so your headlights adjust perfectly to changing loads and road conditions.

URO Xenon Control Unit (Ballast) - Priced Each - BMW & MINI

The URO Xenon Control Unit (Ballast) - Priced Each - BMW & MINI is an essential component for ensuring the proper function of your BMW or MINI’s HID headlights. If you've replaced the bulb in one of your HID headlights and it still isn't working, the issue is likely with the igniter or control unit. The igniter and control unit work together to regulate when the HID lights turn on and begin emitting light, and a faulty control unit can prevent the system from functioning.

• Ensures proper activation and performance of HID headlights in BMW and MINI vehicles
• Designed to regulate the ignition timing for consistent lighting and reliability
• High-quality construction for durability and long-lasting performance
• Replaces a worn-out or faulty control unit to restore full functionality to your headlights
