The headlights on the 350z came in two styles, early model and late model. From 2003 – 2005 the 350z had a weak hybrid-projector low beam that could come with HID or halogen bulbs. But in 2006 and on Nissan upgraded to a new style of headlight that uses a single bi-xenon HID projector system. This newer model headlight looks better and has better light output.
Watch the video below to see how to remove the headlights from your car.
In the first part of this video you can see how the headlights are removed from the vehicle and see that the bulkhead wire connector for both styles of headlights are identical! To upgrade your headlights from your original 2003 – 2005 headlights is as simple as getting your hands on a set of OEM 2006+ headlights, and replacing your original headlights. There is no modification necessary. They are totally plug and play! If your original headlights didn’t have original HID headlights, but you want 2006+ HID headlights, it’s fine – it’s still plug and play. A good place to find OEM 2006-2009 350z HID headlights is eBay, Amazon or a 350z forum.
