DIY:Valenti 3rd/4th Brake Light Mod-Separate Brake light Triangle-2 Options -Video
 

So, there seems to be a lot of threads/questions about how to wire the Valenti 3rd/4th brake light and modify it to work/flash differently. There are wires/cutting/moving/combining/arrows all over etc-I've done this mod before and I was confused by the differences in pictures (upside down/jumper wires all over/new wires added).

When done correctly, there wont be CEL, weird dimming or any other bizarre electrical issues.

There are 3 Main ways of having the Valenti Rear wired

1. Stock out of box-When you turn on the running lights, the "V" AND the center triangle light up. When you step on the brakes, the center triangle flashes 3 times and then remains on. This is less than ideal I suppose, since most of us only want the center part to light up when you step on the brakes-which brings us to the mods we can do!

2. (flashing) When you turn on the running lights, only the "V" will light up. When you step on the brakes, the center light will flash 3 times, and remain on-as long as you step on the brakes. When you release the brakes, the center light will turn off.

3. (Not flashing)When you turn on the running lights, only the "V" will light up. When you step on the brakes however, the center light will turn on-and will remain on until you release the brakes.

The video here shows the different methods AND how the wiring should be setup.
I will have another video shortly that shows which wires to tap into on the tail light side/reverse side-but that content is out there...wasn't a top priority for me. Picture is below

HAD TO UPDATE-WILL ADD NEW PHOTOS HERE SOON

I'll need to check to see how "plug and play" the harness is on the 4th brake light, might just have to pull/tap the red/blue wire into the tail light.

Where was this 2 years ago before I paid someone to mod mine?! Lol jk, thanks for finally posting a DIY on this! :thumbup:

sick, i was finally going to try this over the weekend based on another thread..

let me know if you have any questions on any of this, I tried to make it simple.

The other threads did okay, but it seemed overly complicated in some of them? I don't know lol.

This is the way i wired up for my V and flasher brake

http://www.modbargains.com/images/FR...trobe-1080.jpg

I use a Jumper cable between the black and orange to connect the stop and fog solder point.

I think is essentially the same as your wiring.

But with the way im connected there were interference with some of the electrical system in the car.

on the BRZ..

If you wire it up like how it is in my image.

The moment you step on brake.(well at least on my car)
The boomerang light and side marker will turn on. Also at the same time The clock display go blank.. and the air bag and driver seat sing on the right hand side of the clock will dim.

When you release the brake,
Clock display come back and other light not dimmed.
Boomerang light and side marker goes off.


Another member has notice the same problem, and here are his solution to it.

I didnt get the chance to take it off to try it out yet.



Just want to see if the way your wire up with the Orange and black wire going to Stop and Fog solder point having the same issues as me by using a jumper to bridge it.

Cheers

hmm, I need a brz for testing lol

and, for reference, the jumper method and my method are essentially the same.

The method in question is this?! I BELIEVE this makes sense. Otherwise, whats happening is you set on the brakes with no running/parking lights on and power goes BACK through the system and essentially powers the running/parking lights.

I will need to test and report back, but this does seem to be correct.

Example below:

Remove the green wire from the solder joint(yellow arrow), and attach the red wire to the green wire(light blue arrows).

@j_motion I was wrong!(about the original video/wiring)

I believe removing the green wire from the board and having the red wire connect directly to it is the way to go.

BUT, I will check tomorrow and update the video!

sounds good

thats what mchasteen1 did on his FRS to fix the interference problem

re-shot the video, will have it uploaded tonight perhaps!

okay, new video up with PROPER way to wire!

From now on this will be the new brainer's post to the valenti's install

Just to be clear, is this for the bottom light that FT86 SpeedFactory sells, or is it the legit Valenti light? Or does that even matter?

This is for Valenti lights...so it shouldn't matter as long as its a "valenti" light.

Open it up and see

This is the newer board.
If the board look the same follow the instruction.

If the board look different, you might have to dig through the original
Valenti alternate wiring post
I dont think there are any of the old version on sale right now anymore.

just did this mod again today!

bump-Need your help!

So, it seems that if you have switchback turn signals up front and the flasher relay, it MIGHT cause an issue with the 4th brake light/blinking.

This is a current/load issue-I'm sending pm's to people who might have done this mod according to my video to confirm!

good news! I found an "older" valenti rear light, with slightly different wiring when you open it up. Its the same as some of the other ones I've seen floating around.

Got the wiring figured out, will have photos and video shortly!

I'm plan on doing the blinking version and have switchback blinkers up front. Anyone validate this?

I have one of the older lights with a different wiring from the videos. It sounds like the wiring described in the original thread but those pictures have gone dead and I wanted to be sure. @continuecrushing, were you able to get a video or pictures with the old light you found?

http://i65.tinypic.com/bjdegp.jpg

I'll let @continuecrushing confirm but I'd say you just do the same thing with the blue and red wires. Disconnect them and wire them directly to each other to isolate the V. Then move orange wire over for blink and solid red assuming it works the same as the new version. Just some guesswork though.

I do have photos/video...I'll get that up in a few days! Thanks for the reminder lol, I forgot I had that.

Thanks again for the video. I wired up mine this weekend and this post let me do exactly what I wanted. I have switchbacks inbound so I can test that out. Not sure why that would have anything to do with this circuit. I know some people were having some odd unrelated issues with cheaper led switchbacks.

@continuecrushing any updates on this?

@continuecrushing you had mentioned possibly getting to this over the holidays. Any luck?

Mine works how it should once re-wired when off, v turns on with lights, triangle flashes. But once the car is on, everything still works, except the triangle. The triangle turns on dimly and doesn't flash. What exactly am I looking at here as the issue? Would it be the ground?

Hi,

Is there a way to wire it so the middle triangle doesn't blink but still lights up when I turn on the rear fog light ?

Thanks

Yeah, switch to version 3 and it'll work. I have no idea why it does that. It bugs me that I haven't found out why yet. E


Sure, set it up like wiring 3. BUT, the red wire that comes from the 4th brake light needs to go to the (+) of your rear fog lights. I don't have a rear fog, so I don't know where that wiring is/which wire it is.

So I'm having the issue that a few others have had where the center triangle is really dim when braking. I don't have this issue with the oem tail lights just the valenti tails.

switch to the non-flashing version and it'll be fine.

Hello
Sorry for the late response.

I live in France and rear fog light is something mandatory here, for something called "Technical Control" which we must pass every 2 years (and also the reason I'm here). So every car has to come with a rear fog.

Isn't that the same in the US / on the FRS ? I'd be surprised because the rear fog light look the same on every 86 (BRZ, GT86, FRS)

I have it wired like the version 3 ATM. Back when I wired it, I did not have any difference (comparing mine to yours) so I really have no clue which "+" wire I have to connect it to :/

the stock rear fog light in the US has no bulb in it, or a hole for one.

http://www.ebay.com/itm/Red-LED-4th-...ZZRBAX&vxp=mtr

US doesn't have rear fog for some reason...and our factory lights don't come with wiring or bulb.

As for you, would the "v" being lit up count as rear fog?

I guess what you need to figure out, is how or when you want it to light up. If I had to guess (could be wrong) but the "rear fog" that you have-you have a separate switch that turns it on, right? But at no point does it ever act as a brake light, right?

Let me know how you want it to function, and I can help direct you to how it should be wired.

We could even get fancy (really not complicated, I swear) and make it function as a fog light AND brake light. The way it would work is this: If the rear fog is "off" and you hit the brakes, it will light up. However, if you have the rear fog on, hitting the brakes won't make any difference since it will already be "on"

Thank you guys for the answers.


I don't think the -V- being lit up would count, because it's not as bright as a fog light is supposed to be. (I'm sure you have some cars coming with those in the US, right ? I hope you understand what I'm talking about :) )
It's brighter than the brake lights, so bright it would annoy the cars behind you, when you have it turned on while there is no fog.
**actually maybe as bright as the braking light ? see below**

Yes, we do have a switch to turn on the rear fog light (which is the middle triangle, even on the stock fog/reverse light). It never acts as a brake light, it's something completely different.

Since I installed the Valenti 3rd/4th light, the rear fog light switch doesn't do anything. It doesn't light up the middle triangle, it doesn't blink when I brake (it's not supposed to blink at all since I wired it like the version 3, but this is just for information)




I would like it to function the same way as version 3, but with the triangle lighting up very bright (as a fog light) when I turn on rear fog light switch.
I would prefer if it could not blink while braking and acting as a fog light (at the same time).



Thank you a lot once again !

Edit : After thinking a bit, could it be possible that brake light brightness = fog light brightness ? I really need to verify. If that is the case, we could do what you suggested !

I did my research and i don't think the triangle can be brighter than it is when it acts as a brake light.
@continuecrushing Could you still help me wire it so that the triangle lights up when I use the rear fog light switch ? And no more brake light if possible.

Thank you a lot.

@continuecrushing not sure if this thread is still alive but,

I wired up my 4th light for the V to be alone and for the triangle to flash when braking (following the instructions from the video). However what happens is when I turn on my lights the triangle flashes and stays on without hitting the brakes, and the V does not light up at all. I'm not sure if this is a bad soldering job on my end (I did use a crappy older one), or if I fried one of the nodes.

Wondering if you have any input or advice. Thanks.

I bet the V would light up with the brakes. Try double checking the wiring first, and then switch it. Sounds like it's flip flopped.

Thank you ! I'll try when I have the time.

Is there a way to have the triangle only on when the fog lights are applied? That what i want.

the video posted at the beginning of this thread shows you how to wire the triangle to the brake lights. instead of tapping into the brake power, tap into the fog light power.
