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.

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.
