Yikesai Xenon HID Ballast Kit W3T19371 — D2S Bulb & Igniter, Direct-Fit Plug-and-Play

The Yikesai W3T19371 is a direct-fit xenon HID ballast kit that includes the igniter and a D2S bulb to replace failing factory ballasts on many Acura, Honda, Mazda and Mitsubishi models.

If your vehicle’s HID headlights are flickering, slow to ignite, or have gone dark, a worn ballast or damaged igniter is often the cause. This complete kit — ballast, igniter and D2S bulb — is built to match original equipment fit and function for a wide list of late‑2000s and early‑2010s Japanese vehicles so you can restore reliable xenon lighting without dealer programming.

Which vehicles will this ballast kit fit?

How does this replacement kit restore headlight performance?

The ballast provides the high-voltage pulse needed to ignite xenon bulbs and then regulates current so the lamp maintains stable light output. Replacing a failing ballast plus the igniter and bulb addresses common HID faults like slow start, flicker, or complete loss of beam.

• Includes ballast, separate igniter and a D2S xenon bulb for a complete repair.
• Pre‑tested units aim to reduce installation guesswork and troubleshooting.
• No vehicle reprogramming required; plug-and-play connectors match factory wiring.
• Interchangeable with common OEM numbers to simplify part selection.
