I have an 06 G35x and have a head;ight coming on and off. I think it's the Ballast but my question is if it's seperate from the bulb or not. It looks like I will just buy a new set up I was just wondering if it was all one part or not. Thanks for the help and this has been a great board to read on.

 

the hids are seperate, just need to replace the hid bulb. the ballast is located underneath the headlight housing .
