WRITEUP: 5th gen projector retrofit (finally!)

**UPDATED 2/11/05 - previously missing a whole chunk of info between the shroud section and final cleaning section**

Since no one has posted an official write up (I think) for how to do a projector retrofit on a 5th gen, I decided to document my work which hopefully you find useful. By no means is this the definitive write up since there are tons of different ways and techniques you can use other than the methods I’ve used below. But if you follow the guidelines step by step it should at least get you started and get you through a basic retrofit. So let’s get started.

PARTS

Projectors (what type to use or what will fit has been covered countless times. I personally used Valeos but others that I know have been used are BMW E46, Audi A6, and BMW E55 Bixenons.)
Ballasts and D2S bulbs
Shroud
Phillips and flat head screwdrivers
10mm wrench
Dremel or equivalent tool with cutting bit or ceramic cutting disk
8 x #8-32 3� machine screws
16 x #8-32 nuts
JB Weld (I personally like the JB stick version)
Level
Eye guard
Breathing mask
Electric tape
Plastic knife
Rubbing alcohol

OPTIONAL PARTS

Bezel
Upgraded wiring harness (highly recommended)
Portable power supply to test projector and alignment
Paint if needed
Springs/spacers
High temperature silicone sealant (or ideally OEM sealer available from Nissan – part no. B6553-89915)


PROCEDURES

The first step is to of course remove your headlights (sorry no pictures of these first few steps but I think you can manage). Most if not all the bolts in this step are 10mm so get your wrench ready. First you need to remove the grill. There is one phillips screw in the middle of the grill followed by several clips which you can just pry up with a flathead screwdriver. Next remove the bumper cover. There is one screw in each fender well, several bolts under the car, and finally clips on top that again can be popped up and removed. Next, disconnect and remove your front turn signals (foglights if you have them) and your sidemarkers, then unhook the bumper cover near the fender well and gently pull it forward to take it off (be careful not to scrape the bottom).

Once you have all that off, you can finally get to work on removing the headlights. There are three screws/bolts that hold the headlight. One is on the side of the car, just below the fender (it’s the top bolt of the two), second bolt is on top the cross beam, and the third is on the inside edge close to where the grill used to be. NOTE: This inside bolt is a pain to get off on the passenger light due to the limited amount of space. Once you get all three off, unplug the wiring harness to the low and high beam as well as undo the city light and then gently remove the headlight.

The next step is to open up your headlights. There are several different ways to do this; I personally use the oven method. Arrange the oven racks so you can fit your headlight and preheat the oven to 250 degrees. Once it reaches 250, turn the oven OFF and place your headlight in for about 7 minutes (don’t forget to remove your bulbs first!). Get a flat head screw driver ready and a plastic or crappy knife. After 7 minutes, remove the headlight and the seals should be soft and easy to pry apart. You don’t have to rush, but try to work as quickly as you can while the rubber seals are still soft. Start by lifting all the tabs and then begin at a corner and pry with the screwdriver. Be very careful not to get any of the gooey rubber onto the lens (this is where the knife comes in). As you pry the lens apart from the back cover, use the knife to cut the stringy rubber in between so it doesn’t make a mess. And finally a picture.


Now you can get started on the actual retrofitting work. First, remove the reflector unit from the headlight housing. The reflector is connected by the two alignment screws as well as a ball/socket joint. Using a phillips screwdriver, keep turning the adjusting screws while gently pulling forward on the reflector. Once the reflector is far enough forward, give it a sharp tug near the ball/socket joint and it should pop right out. Remove the alignment screw grommets from the reflector. It’ll save you from stripping the threads and going through the hassle of constantly screwing the reflector in when you want to test fit.


Next, remove that little reflector piece in the middle of the low beam reflector bowl. It’s held by one screw in the back. Once you take this off you can toss this piece since you’ll never need it again.


The next step involves cutting out a hole to fit your projector as well as drilling your projector mounting holes. Again, there are many creative ways to do the actual mounting. I’m too much of an idiot to do something complicated so I stuck to the basic method of mounting directly to the reflector. Begin by making a cutting template of your projector. Place the projector, bulb end down, on a piece of cardboard and trace an outline. Try and keep the lines straight while tracing the outline as it will help you line up the hole on the actual reflector. Cut this template out and place it on the reflector (don’t toss the outside portion of the cardboard which you just cut your template from, you’ll need it again for your mounting holes template).


Use the lines on the reflector (highlighted red) to help you center the template as much as possible. Once you have it centered, trace an outline and this will be your cutting line.


The reflector is pretty sturdy even though it’s just plastic. But needless to say, don’t go man handling it while you do your work. Using a Dremel with a cutting bit or cutting disk, cut the hole you just traced. Tada!


This is just your starting hole to help drill your mounting holes and test mount your projectors. You will eventually enlarge this hole to mount your projector deeper. NOTE: If you plan to keep the reflectors chrome careful not to scratch it up during the cutting and drilling processes. I painted mine black so didn’t care much, as you’ll notice from all the drill slip scratches.

Remember the piece of cardboard I told you to save? Now it’s perfect to use for the mounting holes. Fit the four 3� machine screws into your projector and tighten them down snuggly with a nut.


With the hole in the cardboard, your projector should fit straight through and come to rest on the end of each screw. Mark the location of each screw and this will be your mounting hole template. My four screws corners did not form a perfect square so don’t worry if one or more of your screws seem crooked. As long as you tightened them down firmly, they should be fine.

Cut out this new template so that each mounting hole is at the very corner of the cardboard piece, that way you can just dot the outside corners when you place it on the reflector. (IMPORTANT: These mounting holes you drill for the first time will probably not be the perfect size and will need some adjusting as you begin test fitting the projector. But the more horizontally straight you can drill them the first time, the easier the process of fine tuning the aiming will be. So do all that you can now to make sure they are as straight as possible before you drill them. Remember, your four mounting holes may not form a perfect square so think straight relative to the overall projector. Also, when looking from the top down, see the lines on the high beam reflector running from front to back? Try to align your template perpendicular to these, sort of a like a T, to ensure your projector faces forward and does not fire off to the left or right) Once you’re convinced they’re straight, mark your reflector and drill the holes out (start small, just big enough to fit the screws). If all goes well, you can do your first official test mount.



If you haven’t thought about or finished a shroud and bezel for you projector, now would be a good time to start. This is the biggest area where you can get creative and it all depends on what projector you use so I can’t go into how exactly to do this. But to give you an idea, my shrouds were 3�aluminum elbows bought from Home Depot. Some people choose to JB Weld the shroud over the projector to block all light leakage, but I didn’t like the idea of permanently sealing the projector off so I just cut a template to block majority of the gaping holes on each side.






Once you have the shroud and bezel out of the way, you can begin the final process of fine tuning your mounting. This step takes the longest to get right and ideally should have the most pictures, but honestly there really isn’t anything I can show you. Basically you have the projector hole as well as mounting holes so all you need to do now is keep working with those until your projector fits perfectly and is aligned straight. Once you get started, you’ll know what I mean, but here are some tips.

The projector hole you first cut out, like I said earlier, will need to be enlarged since this initial hole will likely be too small and too shallow; your projector will end up hitting the headlight cover lens. Take a look at the next picture. See how deep the base of my projector is in relation to the top of the reflector bowl? This is about the minimum depth you want to use. In other words I highly recommend you mount them at least this deep, if not deeper (I’m redoing mine this weekend since I’m having problems with the bezel hitting the headlight lens).


Once the projector fits deep enough, work on the mounting holes. This is probably the most crucial step but if you drilled the holes straight the first time, it shouldn’t be too bad. Put your projectors in make sure you can get them to sit and aim straight. Check from the top, do they aim forward (or to the left or right)? Check from the side, are they horizontal (or do they point up or down)? And finally, check to make sure the rotational axis is straight (cutoff beam is horizontal across and not rotated clockwise or counter-clockwise). The best way I found to do this is to use a level. I happen to have a mini one that sat perfectly in the projector. Yup looks straight and level to me.


If one or more of these alignment elements are not straight, enlarge or finagle the mounting holes as needed until your projector is straight. Having a power supply to test the aiming is extremely helpful. I was able to just fire them up in the house and test them without having to go back and forth to the car. But this of course is optional.

It might not hurt to test the aiming with your shroud and bezel in place as well. Once you can get your projectors aiming straight, take them off and get everything ready for final mounting. This includes securing the machines screws, make sure the nuts are tight again and I used electric tape to make sure they don’t come loose. You could use springs or spacers instead to maintain tension or even JB Weld them.


If you don’t like the idea of a gaping hole in the reflector or worried about condensation, you can seal up the hole around your projector (I didn’t, so sorry no picture). You can either tape it up or again JB Weld for something more permanent. Also, if you plan to paint the reflectors, now would be the time.



And finally, take your projector lens off and swab it clean on the inside with some rubbing alcohol. Blow out any lint and then reassemble.


Almost home free! Mount your projector back on the reflector and go through all the alignments again to make sure it is absolutely straight. If they look good, tighten a nut on the back of the reflector on each of the four machine screws. I hand tightened each one as much as possible and again taped them off with electric tape to prevent them from coming loose (or JB weld them).

Once you got the projector mounted on the reflector, mount the reflector back to the headlight (back) cover. Place the alignment screw grommets back on reflector, pop the ball joint back into the socket, and turn the alignment screws to feed through the grommets.

Finally, wipe down the high beam reflector bowl, the inside of your headlight lens, and clean the outside of the projector lens thoroughly (same way you did the inside of the lens, with rubbing alcohol). Beautiful.


Before you seal the headlights, make sure the projector doesn’t butt up against the front lens. Fire the projectors up and do one more test to make sure everything is straight and everything looks good. If so, seal the headlights back up. I just reheated the original seals (oven again) and clamped the lens together. If you want to ensure a tight seal, you can use high temperature silicone or better yet order some OEM headlight sealer from Nissan.

You’re done pimp! Put your bulbs in, put the headlights back on the car, put your bumper cover and grill back on, hook up your wires and you’re good to go!



*** Just a closing note about the wiring harness. I recommend buying an upgraded harness to prevent frying your OEM ones. You can purchase one from suvlights.com or xenondepot.com or make your own. The harness basically connects directly to the battery and ground as well as both ballasts and the final tap is made to the incoming signal from the low beam harness.

Hope this helps and if you have any questions, feel free to contact me or just post up and I’m sure the more experienced retrofitters will chime in.

I still don't understand how the hell you line them up correctly. I've seen more than one write-up and I'm still lost as to how you get it perfectly lined up. I'd do it but I'm affraid that I'd fuk up the alignment or worse fuk up my headlights

i'm also another one can't see how you deal with alignment issues.

I have permanently hosted hundreds of pictures documenting a retrofit for over a year. It may look familiar: http://www.imagestation.com/album/?id=4291002885


Brodie would probably agree that this is not comprehensive. Alignment is a big deal and failure on that part means failure on the whole retrofit.

Crap. I just realized why so many people were confused about the alignment process. I left out a whole section in between the making shrouds portion and final cleaning before reassembly. Sorry, updated the writeup and hopefully that makes more sense.

pIOUs' album also helped me a lot during my retrofit (Thanks Man!). I practically had it as my homepage and even had the Danzka bottles ready . His idea was ingenious and he made his own mounting bracket with slits rather than holes. That way the projector could simply be rotated and locked down once they were straight. But what I lacked in creativity, I made up for with an obnoxious level of attention to detail which should be evidenced above.

BTW. If you only need a few mm of space so that the projector doesn't hit the front cover there are tricks. One is to remove the pivot nut, cut 2-3mm off the treads and shave down the mounting surface. THis will make the reflector housing sit back furthur. The other thing to do it mount the projector from behind the reflector housing. The reverse trick works if you need more rear-side room. It will push it out just a bit. I've always said, that the smallest adjustments make the difference in fitting most of the projectors in these headlights. Have fun with it. Good job in writing this all down and taking your own pictures too. They all came out well.

Hi, any chance we could get the pictures back up on this thread? I would love to use this as a guide.

Thank you,
