Electronics for BMW 3 Series E93 (2007-2013)

Are you tired of the traditional white DRLs that came with your BMW from the factory? Upgrade your headlights with the new Turner Motorsport LED DRL Modules to achieve the highly sought-after Yellow DTM or GT-style appearance!

Turner Motorsport LED DRL Modules offer the first true Plug-and-Play solution for your BMW, allowing you to easily swap them out without damaging your original DRLs. Unlike many options that require you to remove your DRL modules and pry the LED circuit board away from the factory heatsink—risking a bent circuit board and cracked traces—Turner Motorsport’s modules come with a pre-mounted heatsink. This design eliminates the risk and saves time on installation. Plus, if you ever need to revert back to stock, simply swap the modules out and you’re good to go.

These LED DRL modules are designed to work with the factory headlight controllers and wiring. No coding or additional wiring is necessary for a seamless integration.

This kit includes all the DRL modules necessary to upgrade both the driver and passenger side headlights.

Installation Note: Due to the location of the factory modules, removal of the fender liners and/or front bumper may be necessary.

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.
