雪佛兰道奇挑战者 D1氙气灯安定器 10R-034663 替代89025794 全新

Your headlights exhibit delayed start, flicker, or one-sided illumination, or the instrument cluster displays “Check Headlights” fault code; usually indicates the original HID ballast is aging or damaged and cannot stably drive the bulb. The ballast normally steps up 12V to over 23,000V to ignite the xenon bulb and produce a stable bright light for clear night driving. This product OEM number 034663 can substitute the original part number 89025794 and fits Chevrolet, Dodge Challenger, and Audi models. During installation, disconnect the battery negative and ensure interface compatibility between old and new ballast and bulb, to avoid high-voltage shock risk.
