For many years the industry standard in automobile lighting was incandescent light bulbs filled with halogen gasses. Halogen lighting isn’t dead, and the ways it is being updated for use in today’s vehicles is very interesting. Here we will discuss new technology and old methods of using halogen lighting in the automobile world.
The 2003 – 2005 350z headlights came with 2 light bulbs and the option of an HID bulb for low beam or a standard halogen bulb for low beam. The high beams are always the same though in this early style headlight. The configurations you can see on the 03-05 350z headlight are: H7 halogen low beam with H7 halogen high beam. Or D2S HID low beam with H7 halogen high beam. Also, the early model projector is a type of hybrid projector unit.
The 2006 – 2009 350z headlight only comes as one style, and that’s a single, large, bi-xenon (dual beam) projector assembly utilizing a 35w D2S HID bulb. This headlight has a motorized shutter inside that allows the single projector to create 2 beam patterns for your high and low beam function.
In this video we go in depth discussing all the details of these two styles of Nissan 350z headlight housings, what it takes to upgrade them, replace bulbs, and remove them from the vehicle for maintenance:
The best way we found to change the headlight bulbs in your 350z is to completely remove your headlight housings. To do that, you’ll need to remove the bumper. It is possible to get access to the back side of your headlight through the wheel well, but you don’t have much space to work in and the actual replacement job is more difficult this way. if you take the headlights off the car you can easily do a good job at replacing your Nissan 350z headlight bulbs or upgrading your blinker bulbs to LED.
Start by pulling back the front fender liner on both sides of the car.
Reach behind the bumper next to the front wheels and remove the two 10mm bolts attached on the both sides on the bumper. These bolts face up, and connect the top corner of the bumper to the bottom corner of the fender.
Locate and remove the six plastic clips on the top of the bumper under the hood.
At the bottom lip of the bumper locate and remove eight 10mm blots that hold the splash shield.
With the front bumper removed, removing the headlights is easy.
Remove the four bolts: two on the bottom, one on the top, and one on the side.
There is one large bulk head connector that all of your headlight wires plug into that needs to be disconnected. With the headlight housings removed, its really easy to get at your 350z bulbs to change them. Are you looking for new bulbs that are brighter or have a better color? Find 350z headlight bulb replacements and upgrades here. And watch the video below to see the different headlight options and differences.
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.
