This 12V HID Xenon Ballast Headlight Control Module powers the high-intensity discharge bulb in compatible Lexus, Toyota, and Mazda headlight assemblies, replacing a failed or flickering OEM ballast. The 12V HID Xenon Ballast Headlight Control Module regulates voltage to keep the arc stable and the beam consistent.

Overview

This 12V HID Xenon Ballast Headlight Control Module is a direct replacement control unit for factory HID headlight systems on compatible Lexus, Toyota, and Mazda vehicles.

Specs At A Glance

Good To Know

Q: How do I know the ballast is the failed part? A: If the bulb is new and good but the headlight still flickers, dims, or stays off, the ballast module is the usual cause. Swapping a known-good ballast to the other side can confirm the fault before ordering.

Q: Can I install this myself? A: On most vehicles the ballast mounts behind the headlight housing and connects with a factory-style plug, so basic hand tools are usually enough. Disconnect the battery and let the ballast discharge before handling it.

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