This DIY is for those who want to do the 06+ headlight upgrade to their 03-05 z. Here is the list of tools you will need:

10mm socket
socket wrench
extension
patience and time

First we start off by removing the bumper. i don't think i need to go into much detail here as their are many tutorials regarding it and only 3 bolts on each side.



Next, there is 4 bolts you will need to remove. I have them pointed out here:



After that we need to disconnect the lights. Simply use a flat head to push in the little **** on the clip and pull down and it will come out



You should now have your light off and ready to be taken apart. take off the next 4 screws and unclip it



Once thats done turn it around and you will see the following. unscrew it and unclip it also



Once thats done we now need to remove the bulb. simply unclip it and pull it out



You should now have this:



Now attach it into the new light. you can leave the ground wire unhooked (the piece im pointing at thats not mesh), it wont hurt anything. just feed the mesh wire up into the light into the ballast. protip: put the bulb in first, then use the metal things to hold it down for you. then it should just slide down onto the light and turn into place (i was trying to put it all in at once which wasnt working lol)



Everything should now be seated correctly and plugged in:



Put the plastic round piece back on. your gonna have to work with it and try each one if you dont remember how they went



Repeat this for the second light and hook everything back up to the car



Throw your bumper back on and your done

 

keep in mind the bulbs are different from the headlights.

06+ is D2S

03-05 is D2R because its not a true projector but a reflector

 

I must be an idiot, but I cant comprehend what you did here lol. So how did the 03-05 lights turn into the 06+ ones? What did you do exactly??

 

You need new bulbs. The d2s

 

I am a little confused as well. With the stock '06 housings, all I need to do is take my '04 harness and sockets out of my old lights and buy new D2S bulbs to replace my old ones? Is this correct?

 

As long as you have stock 03-05 HIDs, yes.

 

I have an '04 enthusiast with xenon low and h7 high beams.

 

What do you do with the high beam wiring on my '04? How do the high beams come on when they are turned on?

 

Think he may be talking about a bulb upgrade, but I may be wrong.

 

what kind of rims are on your z?

 

I just did mine, make sure you do the headlight adjustment, it makes a huge difference. Do it after you get the d2s bulbs though

 

i cant find headlights or tailights for 08 350z, do the 03-05 fit? thanks im new to this so i dont know if anyone alredy asked, thanks

 

As far as I know they are the same size and shape and will interchange without problems. What are you trying to do with your '08 headlights? PM sent.

 

why did you change the bulbs? i just hooked up an 06 to my 04 and it all works fine without touching anything.. been working fine for 3 years now

 

thanks for the reply , and as u know i have the stock projectors that come with the base 08 so , i wanted to trow in some halos or angel eye,and a blacked out nice designed tailights, i want blacked out tail and headlights.

 

you must have D2C bulbs then as their is no way. Check this,



dont get 03-05, thats a downgrade. buy the 06+ headlights new or wait for them to come up on the market here

Okay, but no one has answered how it switches from low to high beam. Mine has a separate plug for the xenon low and H7 high beams. So if you put the new D2S bulbs in the old xenon plug and put them in the new housings, that still leaves the high beam plug.

 

Or you can modify the base.. Just make your own notch

 

I would like to know as well.. Also the signal light bulb will be constantly on when you turn the headlights on.. Which wire to snip? Thanks

 

Guess nobody knows the answer to this or just doesn't care to answer.....
