Before you plug these ballasts in, make sure your HID wires connecting with the bulbs and the bulbs themselves are in good working condition!
These ballasts 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 a ballast on a working (!) side headlight first and you will see it works perfectly!
