Hello, does anyone know where I can buy a ballast? The ones I see are for the entire kit. I need only one ballast. Any info would be appreciated. Thanks in advance.

 

You can try ebay or ddmtunning.com

 

If its many years old, get a new kit and keep the old as spares. Once HID bulbs hit 100 hours, they break in their optimum color and degrade with each hour of use from there on out. So you're not getting the same output as you did when they were new...

Just some food for thought.
