So I have the 03-05 headlights on my 04 coupe. If I purchased 05-07 headlights, would it be plug in play, and was wondering because the headlights that I am looking at do not include the xenon bulb and ballast. Does my existing setup have those already, or do I need to purchase those as well. Thanks.

 

Yes plug and play switch your ballasts to the new set
