OE-PART W3T23371 HID Xenon Ballast - 35W D4S D4R Headlight Control Module for Mazda CX-5/CX-9
OE-PART: Best Alternative to the OEM HID Ballasts
The OE-PART W3T23371 HID Xenon Ballast Control Module is an aftermarket replacement headlight power unit designed for vehicles equipped with failing factory Mitsubishi Electric ballasts. Engineered to supply power to mercury-free 35W D4S and D4R xenon HID bulbs, this module delivers the standard operating voltage required to restore power to a non-functional headlight assembly.
When an original HID ballast fails due to thermal degradation, internal component wear, or moisture contamination, the headlight bulb may flicker, experience delayed start-up, or fail to ignite altogether. The OE-PART W3T23371 replacement ballast mounts into the factory headlight housing location and connects directly to the stock wiring harness. Operating on a 12V DC input with a rated 35W AC output (42V AC operating voltage for D4 systems), this module offers a practical, budget-friendly alternative available through HID Concept.com for servicing factory-equipped HID headlight systems without paying dealership replacement costs. Sold individually (Pack of 1).

Vehicle Compatibility Section

Part Number References
Mitsubishi Electric: W3T23371
Mitsubishi: W3T23371
Vehicle Application List (Factory HID Xenon Trims Only)
2008-2015 Mazda CX-9 (Fits vehicles with factory HID headlights)
2012-2016 Mazda CX-5 (Fits vehicles with factory HID headlights)
Important Fitment Notice: Designed solely for factory-installed HID Xenon headlight systems. This ballast will not fit or convert models equipped with standard halogen bulbs or aftermarket LED headlights. Because headlight assemblies can vary by trim and manufacturing date, HID Concept strongly recommends removing and visually verifying the part number on your original ballast before placing an order.
Performance & Visibility Section
A properly functioning HID ballast is necessary to ignite and maintain the electrical arc inside a xenon bulb. Over time, original control modules can lose efficiency due to heat cycling and aging electronics, resulting in unlit headlights or unstable power delivery. The OE-PART W3T23371 module delivers standard electrical current to your D4-series xenon bulbs, helping restore reliable headlight operation for nighttime driving safety.
OEM Quality & Reliability Section
Sourcing replacement headlight control modules through HID Concept.com provides vehicle owners with an affordable solution for repairing non-working headlights. Manufactured to match stock electrical specifications and factory mounting footprints, this control module carries an estimated service life of 2,000 hours.
Service Recommendation: Because opposing headlight components accumulate equal operating hours, HID Concept recommends testing both headlight ballasts and inspecting bulb condition whenever performing lighting system repairs.
Installation Information
The OE-PART W3T23371 ballast features a direct plug-and-play layout designed to match the factory mounting locations and plug connectors on compatible vehicles.
To install, ensure the vehicle ignition is OFF and power is disconnected. Access the headlight housing, remove the failed original Mitsubishi Electric ballast, attach the factory harness connector to the new OE-PART module, and secure it in place using stock mounting hardware. No wire cutting or custom software coding is required.
