Our D4S HID Ballasts can be used as a replacement for the Toyota 86 GTS or Subaru BRZ HID factory ballasts. They can also be used if you need a set of ballasts when installing factory GTS/BRZ headlights onto a Toyota 86 GT model.
A ballast is a crucial part of a fluorescent or HID lighting system. Ballasts have been used in lighting for decades, and more frequently in HID lamps as HID headlights have gained popularity.
In a fluorescent lighting system, the ballast provides the voltage needed to start the lamp and regulates the electrical current of the light once it is lit. Without a ballast, the lamp would draw too much power, causing it to burn out quickly – sometimes even within a few minutes. The ballast prevents this from happening and ensures you get the benefits of the lamp’s full lifetime.
Our D4S HID Ballasts are sold as a pair and have a 1 year replacement warranty.
