MOTOALL Xenon HID Ballast Assembly W3T15671 with Igniter & D2S Bulb — Aluminum Housing, Waterproof Circuit

High-performance MOTOALL W3T15671 Xenon HID ballast assembly replaces worn HID control units and restores reliable headlight ignition and brightness. This complete kit from MOTOALL includes the ballast, igniter, and a D2S xenon bulb engineered to match OEM electrical and mounting specifications for selected Acura, Honda, Mazda, and Mitsubishi models. Built with an aluminum housing and an adhesive-treated waterproof circuit board, the unit improves heat dissipation, reduces corrosion, and resists vibration for longer service life. It is designed as a direct-fit replacement for multiple part numbers so you can replace a failing ballast without modifying the vehicle harness or headlamp assembly.

Which vehicles and part numbers does this ballast fit?

The MOTOALL W3T15671 is compatible with a range of late-2000s to early-2010s Acura, Honda, Mazda, and Mitsubishi models. It directly replaces many factory part numbers, simplifying identification and ordering.

• Replaces: 33119-SEP-H01, 33119-SAA-013, 33119-TA0-003, 33119-STK-A01 and W3T-series numbers listed.
• Fits: Acura TL/TSX/ILX/ZDX/RDX/MDX, Honda CR-Z/Odyssey, Mazda CX-5/CX-9/3/5, Mitsubishi Outlander/Lancer Evo.
• Designed for D2S xenon bulb systems requiring a ballast and igniter assembly.

How does this ballast improve headlight reliability?

The assembly uses a treated circuit board and an aluminum housing to protect electronics and dissipate heat. This lowers the chance of premature failure from moisture, oxidation, and vibration commonly experienced in factory units.

• Waterproof circuit board with adhesive potting for corrosion protection.
• Aluminum shell for improved thermal management and rigidity.
• Six built-in electrical protections to guard against common faults.

What’s included in the package and what should you expect during installation?

The kit arrives ready to install with the ballast, the separate igniter, and a vehicle-compatible D2S xenon bulb. It’s intended for plug-and-play replacement where the original connectors and mounting points match.

• Box contents: 1x ballast control unit, 1x igniter, 1x D2S bulb.
• Basic installation: remove old ballast/igniter, mount new unit, connect harness and bulb.
• No extra wiring or adapters required for matching OEM-equipped models.

Will this ballast work long-term and how is it protected?

The ballast’s construction focuses on durability: conformal adhesive treatment secures internal components and resists moisture, while the aluminum case reduces temperature stress and vibration-related failures. These features aim to extend functional life compared with untreated units.

• Adhesive irrigation over the PCB prevents oxidation and reduces loose contacts.
• Rugged housing fights vibration and improves heat dispersal.
• Engineered protections help mitigate short circuits, overvoltage, and other electrical faults.

Who this is for: If your vehicle is equipped with D2S xenon headlights and is listed among the compatible Acura, Honda, Mazda, or Mitsubishi models, this MOTOALL ballast kit is a direct replacement option. It’s suited for DIY mechanics and professional installers who want an OEM-style fit and a more robust, moisture-resistant assembly than many worn original units. Choose this kit when you need a plug-and-play ballast, igniter, and bulb solution that prioritizes corrosion protection and thermal performance without rewiring the headlamp system.
