Replacing the Xenon bulb in your AFS HID headlight assemblies are relatively easy but can be tricky. In this video, I explain a few key things you need to know to make the replacement a breeze. By "ballast", I mean "igniter". Igniter is the correct name of that square part only. In some cases, the ballast which is the Xenon lamp control module comes with the igniter integrated, as one piece called "ballast". In our case, the actual ballast or control module is mounted at the bottom of the headlight assembly.
