Yikesai Xenon HID Headlight Ballast W3T19371 with Igniter — Direct OEM Fit, 35/50W

The Yikesai W3T19371 Xenon HID ballast with igniter is a plug-and-play replacement module that restores reliable startup and stable output to compatible Acura, Honda, Mazda and Mitsubishi HID headlights.

If a vehicle’s HID bulb flickers, fails to light, or throws a headlight error, a worn or faulty ballast (and its igniter) is often the cause. This Yikesai assembly supplies the high-voltage surge to ignite xenon lamps and then regulates the lamp current so the bulb maintains steady brightness. It’s engineered to match OEM fit and electrical specifications for many mid-2000s to early-2010s Acura, Honda, Mazda and Mitsubishi models so you can swap it in without custom wiring.

Which cars and years will this ballast fit?

This ballast is compatible with a wide range of models across Acura, Honda, Mazda and Mitsubishi lines. Fitment covers popular sedans, SUVs and crossovers from roughly 2004–2014 depending on the model. Always verify your existing part numbers before purchase.

• Acura: TL, TL-S, TSX, ILX, ZDX, RDX, MDX, CSX (model years listed in full product specs)
• Honda: CR-Z, Odyssey, Accord variants and other listed models
• Mazda: CX-5, CX-9, 3, 5 and other compatible platforms
• Mitsubishi: Outlander, Lancer Evolution and selected year ranges

How does this replacement match the original part?

The Yikesai unit is built to meet or exceed common OEM standards for size, connectors and electrical output. It replaces numerous factory part numbers so it installs into the same mounting points and plugs directly into the headlight harness. The internal circuitry keeps lamp power at a steady 35W or 50W range as required by the HID system.

• Interchangeable with many factory part numbers (examples include several 33119 and W3T series numbers)
• Designed for left or right headlight locations where applicable
• Electrical regulation protects HID bulbs from over- or under-voltage

What’s included and what can I expect after installation?

Each order includes the ballast module paired with the igniter assembly and backed by a 12-month warranty. After replacing a failing ballast you should see consistent lamp ignition, elimination of flicker or error codes, and restored beam stability.

• One ballast and matching HID igniter per set for direct swap
• Pre-tested units to reduce DOA issues out of the box
• Manufacturer support and a 12-month limited warranty for peace of mind

Is installation difficult for a DIYer?

Installation is typically straightforward for anyone comfortable removing headlight housings and unplugging factory connectors. No cutting or splicing is required when the part number and connector match; however, bulb handling and high-voltage circuits require caution.

• Plug-and-play connectors match OEM harnesses for compatible models
• Requires basic hand tools and safe handling of xenon lamps
• If unsure, professional installation is recommended to avoid damage

Who this is for: Drivers with flickering, slow-starting or non-functioning xenon headlights who need a direct-fit replacement ballast and igniter. It’s aimed at owners of compatible Acura, Honda, Mazda and Mitsubishi vehicles who want a reliable, OEM-compatible module without hunting for discontinued factory units. If you own one of the listed models and have confirmed the ballast as the fault, this Yikesai kit offers an economical, tested solution that restores proper HID performance.
