Yikesai Xenon HID Headlight Ballast W3T19371 with Igniter — Direct-Fit Replacement, Stable Ignition

Yikesai W3T19371 Xenon HID Headlight Ballast with integrated igniter is a direct-fit replacement that restores stable HID ignition and consistent light output for compatible Acura, Honda, Mazda, and Mitsubishi models.

If your HID headlights are flickering, taking too long to start, or have stopped working altogether, a failing ballast is often the culprit. This aftermarket Yikesai ballast is engineered to match the electrical characteristics of the original unit, delivering the voltage spike needed to ignite xenon bulbs and then regulating power to keep output steady. It replaces common factory part numbers including W3T15671 and W3T16271 and is designed for plug-and-play installation on the specified vehicle list.

Will this ballast fix intermittent or slow-starting HID lamps?

Yes — a worn or faulty ballast commonly causes delayed startup, flicker, or loss of beam on xenon systems. Replacing the ballast and igniter assembly re-establishes the proper ignition sequence and stable current for the bulb.

• Restores fast ignition and reliable light output
• Regulates output at the correct wattage to protect bulbs
• Includes igniter and wiring pigtail for complete function
