Perspex sucks!!! I got it from bunnings.

If you can get polycarbonate/lexan, that material is less likey to shatter.

I cut it with a bandsaw at bashers workshop, the inside ring, I just drilled a crap load of holes with drill then used the drill to cut between the holes.

Then just gave it a quick file. It's rough, but beats paying $1200+ for nismo's.

Cost:

housings $250 (I didn't want to pull mine apart)

perspex $35

90 LEDs $78 (jaycar electronics)

resistors and diodes $4

silicone $12

I'm hoping the will be bright enough! In hindsight I should of tried the brake lights in the sun to check brightness....

Thanks for the break down.

I've got plenty of housings which is good :D

Where did you buy the LEDs?

My usual spot for random things is eBay, but someone recommended in the thread not to.

So cheap on there.

What MCD LEDs did you go for? - you're hoping they're bright enough! Let me know haha.

From jaycar, and they are 4000MCD.

Lol, I put in in the last page of my post....

Cool, yeah I had a brief look in ebay..meh

My tip for the day is keep an eye on the oven, if you smell plastic....RUN lolz!!!!

I see you printed the circuit boards for your LED Taillight conversion was it difficult?

Can you make some for the R34?

Making good boards like this is pretty easy if you have the right tools ,

Sneaky trick running 3 LED's rather than 4 in each string allowing the brightness level between Tail and Stop to be a reasonable contrast.

I'll be placing some LED's up the rear pillar on my Axis this weekend if I'm not on the road, so I had best take some pictures as well :)

i was thinking about doing it mass produced wise, had the patterns all stored in the cutter and everything and and even have a 70% finished set sittign in my room with male adapters for the factory plugs.. so much CBF though

Has anyone used Red LEDs instead of the clear ones in their tail lights?

The current prices at Jaycar are -

White waterclear LEDs 4000mcd = $1.90/25+ LEDs, x100 the total is $190

Red waterclear LEDs 4000mcd = $0.99/25+ LEDs, x100 the total is $99

(correct me if I'm wrong)

My understanding is that only the red light produced from a white LED is going to pass through the stock red tail light lense. Where a higher percentage of light from a red LED will will pass through the red lense.

So in saying that, would a red LED should be perfectly fine behind a red lense?

Any update on your LED DIY?

IME using white leds behind a red filter will give a pinkish red. Its not a proper brake light colour at all. Much better to use red leds in the first place.

Also those prices at jaycar are criminal. No way is a single 5mm led worth $1.90 per led (bulk price too!). I dont even bother with jaycar anymore unless there is a single item I need right away, the prices are far too high.

I have found regular lensed leds to be quite reliable from china off ebay. We're talking 100 of them for about $2. As long as you drive them conservatively, perhaps <50% of their rated current, they should be fine for many years.

I have never had a regular lensed led start flickering (and eventually fail), unlike SMD leds which I have seen many times.

I suspect part of the issue is that ebay led light packages come with too low resistors, and so the lights are being driven harder to be made brighter, but at the expense that a higher % of them will fail.

Any update on your LED DIY?

No not as of yet, car has been at my mechanics for many months so I haven't had a chance to get started on it. I will be doing a Nismo R34 led layout on an early tail light (afterburner) HR31 Skyline.

Let me know when you start working on this R34 LED project

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
