ADP Xenon HID Headlight Ballast Assembly W3T10471 with Igniter & D2S Bulb — Plug-and-Play OE Fit

This complete ballast assembly is designed to restore bright, stable high-intensity discharge lighting when an original ballast or igniter has failed. Built to match OE electrical and mounting points, the unit aims to fit directly into compatible vehicles without modification. Each assembly is bench-tested for function before shipping to reduce installation returns and minimize troubleshooting time.

What vehicles does this ballast fit?

The ADP W3T10471 assembly is listed for many Acura, Honda and Mazda models from the early 2000s. Always confirm the part cross-reference or compare your original part number before ordering, because some model years used different ballast variants or sizes.

• Fits Acura TL 2002–2005 and Acura TL Type-S 2002–2005
• Compatible with Acura TSX 2004–2005 and Honda S2000 2004–2009
• Works for Mazda 3 2004–2006 (verify 2006 model; some use a smaller ballast)
• Cross-references W3T10471, W3T12472, W3T14371 and OEM numbers listed

How reliable and OEM-like is the replacement?

This assembly is manufactured to meet strict fit and function requirements so it behaves like the original equipment unit. Materials and connectors are selected to match factory durability and electrical characteristics, and each item is tested to ensure consistent output and startup reliability.

• Engineered to OE mounting and electrical specifications for direct replacement
• Includes igniter and D2S bulb pre-installed to simplify replacement
• Bench-tested before shipment to confirm proper operation

How difficult is installation and what should I prepare?

Installation is typically straightforward for anyone familiar with headlight assembly work because the unit is plug-and-play. No coding or ECU programming is required; simply disconnect the defective ballast, plug in the replacement and secure it using the original mounting points. However, basic hand tools and safe battery-disconnect practices are recommended.

• Plug-and-play design—no programming required
• Use the vehicle’s original fasteners and wiring harnesses for fitment
• Disconnect battery and follow vehicle service manual safety steps
• Inspect connectors and headlight housing seals during installation

Which part numbers does this replace and why check them?

The ADP unit cross-references several factory and aftermarket part numbers so it covers multiple OEM variants. Verifying your vehicle’s existing part number ensures you receive the correct physical size and connector layout—especially important for models like the 2006 Mazda 3 that sometimes used an alternate smaller ballast.

• Replaces W3T10471, W3T12472, W3T14371, X6T02971, X6T02981, X6T02993
• Compatible with Honda/Acura OEM numbers such as 33119-SCC-003 and 33119-S0K-A10
• Also cross-references Mazda numbers D391-51-0H3 and C236-51-0H3
• Confirm the part sticker on your existing ballast before purchase

Who is this for? This ADP ballast assembly is aimed at vehicle owners, independent mechanics and repair shops replacing failed xenon ballast/igniter units in compatible early-2000s Acura, Honda and Mazda models. It’s a practical choice when you want an OE-style fit, a pre-installed D2S bulb for faster turnaround, and a tested unit backed by 18 months of after-sales support.
