What is the purpose of a headlight control module (ballast)?

The control module, also known as a ballast, is essential for operating xenon (HID) lamps. It provides the high voltage needed to ignite the lamp and then regulates the electrical current to maintain a stable light output. It also contains safety circuits to protect the system.

How do I know if my headlight control module needs to be replaced?

Common signs of a failing control module include a headlight that flickers, dims, or doesn't turn on at all. If one headlight works but the other doesn't, and you've ruled out a burnt-out bulb, the ballast is a likely culprit.

Does this module come with any installation hardware?

This part is designed as a direct replacement for the original module and typically installs using the existing mounting points and connectors. Refer to the manufacturer's installation instructions for specific details regarding hardware and procedures.
