Well, I started this little side project last night. I did a lot of reading and research and admittedly I don't completely have my head wrapped around everything I need to know, but overall it seems pretty straight forward. This is an extremely useful thread if you are considering doing this and have never done it before:
http://www.ziptied.com/forums/index.php?topic=14205.0

Now, IMO the stock G50 tail have always looked pretty horrid. So I picked up a spare set from the junkyard for $25 :)

Here's the stock tail light:

Image

Once you have the tail light removed you'll notice a rubber seal that goes around the light, you'll need to carefully remove this:

Image

Once removed you'll have access to 4 clips (two on top 2 on the bottom), and this is where it gets tricky, excuse the flash:

Image

Now, you'll need to stick it in the oven at ~200 degrees on bake for about 5 min. This will help soften the goo holding the lens in the housing. Once nice and warm you'll need a small flat head screw driver and gently depress the locking clip while slowly (and i stress slowly) prying the lens away from the housing. You'll probably need to to reheat a few times to remove it without breaking it, this grey/white goo is not soft like the black goo that seals the housing to the chassis and takes some patience to get the lens free.

Once removed you'll see this:
Image

There are two separate diffusers behind the lens. Be careful not to break these when pulling them out you will need to reuse them after some modifications.

Image

IF YOU DO NOT WANT TO BUILD A LED BOARD AND SIMPLY USE A LED BULB, STOP HERE! Simply leave the diffusers out of the tail lights and press the lens back in! You've got a great updated looking set of tail lights, just be sure to use a VERY Bright led replacement bulb.

Here is what the tail lights look like without the diffusers! Such a huge difference!

I ordered all of the supplies, led's, pcb boards, etc which will hopefully be in by the weekend. I'll update the thread as the project progresses!

Ok, finished the pass side rear brake/parking lights, pics as promised!

Here is just the parking lights:

I forgot to mention.. here is everything I am using to build these:

Parking Lights = 12k mcd, red, 5mm

Brake Lights = 30k mcd, red, 5mm

Turn Signals = 12k mcd, orange, 5mm

You can use clear as well if your lens is colored, but from what I've read, red leds make the light out put more crisp vs white leds.

Resistor = 330ohm (for 3 leds)


I decided to run these in parallel series (3 leds in series).

Here is what it looks like, however I'm not sure why the resistor is on the - side, it should be on the 12v side.

Image

This website kicks a** and is easy to calculate the correct resistor needed if running multiple leds in series:

Nice effort not realized here before.

However, it increases my appreciation of old incandescent technology, especially aesthetically.

Looks like its coming out pretty good. You have to decide if the time taken in making these is cost effective enough. They can be had out of Japan and shipped to your door for around 125$ believe it or not. Ya gotta look in the right places.

BCC93Q-where do you find this stuff? Do you actually have those lights? 125/pair? how do they affect the lamp out sensor?

Yes I have them but I dont have them installed. They are for the LATER G50 I have a 1992. Everything listed under the link in my profile is currently in my possession + more I have not uploaded. Everything I have sold out of it has been removed into a different folder. Shipping is the biggest issue when shipping from japan

I can't attest to the ones BCC posted, however mine are at a minimum 2x's as bright as oem, which are pretty dim imo. I removed the brain for my gauge cluster display since my ABS and Trac is gone, and brembos would have set the pad light off too.. just not worth keeping it. Otheriwse I would let you know if the light comes on.. haha

Hard to show brightness in pics.

Very nice! One of my projects I've never started. I have a sleeve or two of Luxeon High Flux LEDs sitting around for "someday"

At this point I'm thinking the aftermarket blub replacements might be good enough for me. They have gotten a lot brighter in the five or six years.

I just installed the led tail lights you sent me. I smoked them then put them in. WOW, these are so bright. They are worth every penny I paid for them. They are truely amazing looking. I'm having a professional rehab the jdm head lights you sold me. We are thinking projectors, and custom painting them. Thanks again for helping me waste even more money on the Q.

Actually, I kinda would like to get my hands on a set of those LED tails,as in my opinion,the OEM are borderline deficient as far as light output on the tail lamp portion, and this mod would actually Improve visibility and safety.Still have not heard the proper solution to avoiding the lamp out indicator thinking you have a burned out bulb yet.......do you actually have another set of these and the high mount center led CHMSL in your hands? Price for all 3 ?????

Go for it. You will be very happy! The brightness is unreal, and mine are tinted.
as far as photo's once my head lights are done and on I'll get some pics up of the whole car. Not many of us old guys here anymore.

Am working on my next crate from Japan. They sell instructions in Japan how to remove the "defusers?" Unfortunately it is in Japanese... Batch will be arriving in mid to late January. Need to fill it to be the most cost effective. Will have a few sets to sell

If you are going to do the projector mod behind the clear lens {only real way to get a proper beam with the JDM lights}, stay away from the Morimoto and other chinese junk- Hella makes high quality projectors at reasonable prices....see www.rallylights.com for options/prices.


How did you get around the "bulb out indicator" issue with the LED tails?

Thanks for the info. that really helps.
I wired in resisters. Not the best idea but it did work. I would like to find another way.

While those dont look bad,I think the q45 ones{with red on bottom/amber on top} would match up better with where the center red reflector is located on the trunklid better?

Fluctuates man. Some sets sell for different amounts depends if they are new/used/defusers removed ETC. Cannot quote until I pay for the crate to leave Japan. I pay buy weight
