I found some guy selling a ballast/ignitor and the headlight adjuster on Ebay. My question is, will fit directly on the OEM non HID headlight housing without any problems?

 

the ballasts and the hid bulbs...... you can make it work with your car... but your would have to grind the hid bulbs housing so that it fits into your oem 9006 bulb housing...

are they selling the headlight+ballasts+hid bulbs???

or just ballasts and hid bulbs... if they are just just these 2 things then follow my steps on top

if they are selling the whole headlight with ballasts and hid bulbs.. then you should be able to just bold on the new head light... connect the positive of the ballast wire to the positive of your old bulb wire and the negative one to the negative on your car......
