PLEASE DO NOT TROUBLESHOOT YOUR LIGHT WITH OUR PART!!!
Before you plug this ballast in, make sure your HID wire connecting with the bulb and the bulb itself are in good working condition!
This ballast can be easily burned by a defective bulb or HID wire!
It has happened before! We’re recording a video of testing every single ballast before we ship it so if you burn the ballast with a bad bulb or wire it’s not our fault!
To be absolutely safe, install this ballast on the working(!) side headlight first and you will see it works perfectly!
