If your vehicle’s headlights have been flickering, dimming, or shutting off completely, the culprit is often a failed xenon ballast. The RANSOTO W3T19371 Xenon Headlight Ballast is engineered to restore full brightness to your HID lighting system without the dealership price tag. This direct replacement ballast works seamlessly with Acura TL, TSX, ZDX, and MDX models, along with Honda Accord, CR-Z, and Odyssey, plus Mazda CX-5 and CX-9, and Mitsubishi Outlander and Lancer Evolution vehicles equipped with D2S bulbs.
What sets this ballast apart is the integrated igniter design, which eliminates the need to purchase separate components. You get everything required for a complete repair in one package, saving both time and money. The unit delivers stable voltage to your xenon bulbs, ensuring consistent light output and extending bulb lifespan. Installation is straightforward for anyone comfortable with basic automotive electrical work, with plug-and-play connectors that match your factory harness. The ballast replaces OEM part number W3T15671, making fitment verification simple.
Who Is This For?
This ballast is ideal for drivers experiencing headlight issues on compatible vehicles who want to avoid expensive dealer repairs. If you’ve noticed one headlight working while the other stays dark, or if your lights take several seconds to warm up and stabilize, a failing ballast is likely the cause. DIY mechanics will appreciate the direct-fit design, while those who prefer professional installation can hand this to any shop for a quick fix. It’s also perfect for anyone maintaining an older Acura, Honda, Mazda, or Mitsubishi who wants to keep their xenon headlights functioning safely.
