Xenon Headlight Ballast HID Control Unit Computer Module For Jeep Grand Cherokee

Xenon Headlight Ballast for Jeep Grand Cherokee

This HID control unit computer module powers the xenon headlight bulb on compatible Jeep Grand Cherokee models, delivering the high-voltage current the lamp needs to ignite and stay lit.

Overview

This xenon headlight ballast serves as the control unit that regulates voltage for the factory HID lamp on the Jeep Grand Cherokee. It steps up battery voltage to strike the arc inside the bulb and holds output steady once the lamp warms up. It suits drivers replacing a failed, flickering, or moisture-damaged HID control module.

• Regulates output current to keep light color and brightness steady
• Sealed housing resists moisture, dust, and road spray

Specs At A Glance

Good To Know

Q: How do I know the ballast is the failed part? A: If one headlight will not ignite or flickers while the other works, the ballast on that side is the usual cause. Swapping the ballast side to side is a quick way to confirm it.

Q: Does this include the bulb? A: No, this listing covers the ballast control unit only. Reuse your existing bulb if it still works.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
