So one of my ballasts went out, I tried the bulb from the working light and it wouldn't work, so I'm pretty sure it's the ballast.

My question is could I simply replace it with this one? My HIDs are stock.

PS if anybody has one for sale I'll take it off your hands.

 

I just had one go on my Z. It only cost like 80 bucks for a new one.Just go to your local garage and they should be able to find one.
