DIY Sequential LED Turn signals for any car.

Turn your boring fully functional turn signals into cool turn signals.

Tutorial for LED calculator:
- Vbat is the the domain and can be changed by dragging the black circle to the left. R is the resistor in series with the LED(s).
- Vled is the nominal forward voltage of the led, note the graph on the left is the the led voltage deviation by 5% since no LED has an identical forward voltage.
- nLEDinSeries is the number of LEDs connected in series, Note that increasing this value too much can sent the current into the negatives, this means the voltage isn't high enough to light all the LEDs.
- Vmin is the car's battery voltage when off.
- Vmax is the car's battery voltage when on and the alternator is active.
- VledMaxCurrent is the LED you're using maximum current. 5730, 1W and 3W LEDs have a max current of 150mA, 300mA and 700mA respectively.
- The purple region is the range of currents the LEDs will be seeing. It is okay to exceed the LED's and resistors rating simply because in a car's turn signals there on 50% of the time which stresses them half as much as it would if they were continuously on.
Falstad: www.falstad.com/circuit/circu...
I have pasted two circuits here, one is the full simulations and another is a simple demo. In real life the capacitor discharges almost instantly during the off portion of the turn signal sequence, but Falstad treats capacitors as IDEAL capacitors and doesn't discharge them. This is why the demo is a little different than how it really looks. The full simulation has a artificial switch that discharges the capacitor during the off portion which in real life happens naturally so that part isn't something you have to build.

This video is completely irrelevant for BMW drivers, since they have no idea what turn signals are.

[@knightking69]

Shaneoblack😂😂👍👍🤣🤣

[@Sekhar_Home]

Why? BMW has automatic turn indicator?

[@garrygemmell5676]

And Mercedes, Lotus, Ferrari, Maserati, Lamborghini!

[@yossufapp]

@@Sekhar_Home nope, they don't know where the turn signal switch is, cuz simply they don't use it 🤷🏻‍♂️

[@cryo2156]

BMW driver here, what's a "turn signal?".

[@peterbarati7748]

Wtf this guy is actually smart

[@chockyman3858]

Dude's rich, has 300 iq and is decent a video game about tanks in his 20s, this guy is speedrunning life

[@adamwrong7791]

I love how you made a instructional, informative, yet funny video all at the same time lol

[@Twas-RightHere]

That's a nice Audi.

[@cryo2156]

it's a Mercedes

[@dannysalas6690]

I thought it was a Cadillac

[@swiperr9808]

lowkey thought it was a bmw

[@ryosuketakahashi1749]

Look at these noobs not recognising a mustang

[@FJview]

Didnt know that audi has changed the logo.. Quite nice isnt it

[@ripem1417]

Once I saw the graph I knew this was going to be way too complicated for me

[@TheV8Pumpkin]

Dude you deserve SO many more views. You clearly know what you are doing and love it as well

[@gustavpettersson3856]

Wait. Wasnt this Chrisfix channel? Im kinda confused right now

[@1987FX16]

Nice electroboom feel. And great video that helped me make my own tail lights. I subscribed.

[@larryllorenzo]

I have been wanting to do this for my rears for at least a year, but my electrical engineering skills are garbage. After what has felt like an eternity of googling, I gave up and bought cheap chinese sequential. One just burned out and I found your video! Thank You 1000X!!!

[@DwayneHicks426]

I need to make a blue sequencial strip for my ghost busters pack. I'm glad I found this.

[@Biyou22]

this is wildly entertaining and informational lol subbed

[@TheUnlocking]

I think this guy is nuts...lol...but he knows his stuff. Kudos man!

[@user-su3jy9el2v]

Ah yes very good vidio منةسزجصكخز9:11 lengt best🤗🕋🇮🇶

[@moroccantodeath5191]

hahahahha osama bin laden

[@yobonez]

this so entertaining keep up this content i love it

[@mountainman6172]

Thinking of doing this to my missus Fiat 500s. You're a star. Cheers mate!

[@TCreatorO]

This guy is awesome! Just found him, 1st video I see and had to subscribe! Btw thats a nice E92 audi

[@igsgarage]

Actually learned a lot. Thanks!

[@enigmista994]

dude the intro song... u a man of culture

[@AirborneRangerZz]

After watching all of your WoT vids, I find this one and come to conclusion that you're a fucking genius after all.

[@ralphradyk6970]

Nicely done ✅ it’s nice looking Audi bro

[@prorez-retrofit]

The most awesome custom-made sequential light ever!!!

[@Headlights.restorations]

You should do more of these videos.

[@jordanw4875]

I have no idea what you're talking about and will probably never do this because am dumb but this is entertaining regardless

[@Mahmoud.Jehad.Nassan]

What ?! Your DYI channel now "better than Indians tutorial 😂"

[@josefaschwanden1502]

exactly my thought.

[@MattYoung1988]

This is awesome. Do you have a video specially on how to build the Sequencer circuit??

[@Azukaae]

You're my new ElectroBOOM

[@orlinchirinos1981]

Nice 👌 diy LED sequential turn signals with humor 😂

[@thedeep8693]

Can you tell me which op-amp and transistors and capacitors you have used..it would be a great help.

[@ethanconnor7530]

Thanks Osama very cool !

[@fujiwaraj.8494]

i enjoy this content

[@mr.abrams9885]

Good thing yo watch at 2 in the morning but im not complaining

[@zocca0134]

You're not alone... 2 in the moring is my favourite time for youtube videos

[@RaisinBarXZ550]

After way too long I finally bought a soldering iron and now I'm way too confident and I'm going to build these but to put behind the reflector strip on my car because it's a nice shape to wrap around with a strip. I suspect many challenges especially because I can't just slip it in and I have to do some painful cutting

[@amit_diyretrofit5930]

Very nice nad bright turn signals made.....But please post driver components and PCB connections

[@migzzymototv7381]

Nice one bro... ;)

[@jesusmurguia]

Hello, Excellent video requesting your kind help, could you help with the complete schematic, and the values of each of the components, I cannot see where the Integrated Circuits are placed, waiting for your kind response. Best regards

[@livedavid2]

Really entertaining and informative video!

[@zeetech2024]

Hi, nice video... Appreciate it... :-)

[@lilmidgey6927]

God damn that audi is nice af

[@gadget069]

I think I almost learned something :)

[@bxndxlx4150]

No my dog didnt.

[@bxndxlx4150]

I really like that Mercedes.

[@Victor.Channel]

God dame great video

[@ledmk2]

Nice made,

[@01arron]

Hi I’m looking for help. My rear brake and park light as one single pole bulb, I’ve put them in and they light up for the brake light but as for the park light which should be on the whole time when lights are on don’t seem to work, I’m guessing the voltage is too low, what can I do please help would be great

[@CriCKiD3]

bro i've always wanted to do this! and i finally found. a video from scratch. and now i dont want to do it jk but holy looks complicated af!!!

[@ipadm5106]

What do you use to test the leds outside the car? A 12v DC adaptror?

[@djdeex-mansfreestylemusicm7815]

This guy was clearly the nerd of the class.

[@amogus7277]

last time i checked this channel it was august. What has happened lmaoo

[@claudiowarrens]

What brightness are those LEDs you used in your final design?

[@zeetech2024]

Could you please tell me which Transistors and Op Amps you used on the circuit?

[@carriagemaker]

So, how do you make an sequential turning light that only have 4 running sequences each 1.2 second as the old Thunderbird?

[@RC-rg3vz]

How do you get the knowledge of amps and electrical to do this? Trying to learn as much as I can

[@mojihk818]

Is it a program that we can get the output of programming code by designing car light blinker? Please help because I need it very much

[@sekiadigicel]

Hi Awesome work, so which transistor did you end up changing to and the capacitor you’re using towards the end I’m a noob at electronics 😆 cheers

[@led9552]

[@LoverKittey]

Well I mean it is cheaper than buying the custom indicators. Also when's the unicum guide to desmos coming

[@uvwuvw-ol3fg]

Is there a heat sink on LED's to improve efficiency and light output?

[@Rendraled]

How type ic you have to put the ic controller sequential. I mean what the type IC do you connect to the board. Maybe ne555 or else

[@enruoblem]

Great work your genious. Hope u can share the schem diag

[@LorDRangeL97]

I have a question, can you use this "controller" with a led strip?

[@tylerkimdura6690]

Thanks 😊

[@Blerpbloop]

Can you sell sets online? I would buy a set immediately! Would be so cool if you made custom sets for various cars. Thank you for such a great video and explanations.

[@sahan2860]

This deserves a big sub and like

[@rebirthsolutions]

Any way you can drop a list of things you bought? Id love to make the circuit board smaller

[@GHOST07071]

CarCar's adventures

[@thestateofreal2533]

No LED driver? It’s the number one killer of LED’s variable currant?

[@nenerka2586]

Hi. Can you download a good quality scheme? I do not read the component.

[@amit_diyretrofit5930]

Any easy way to make the controller. I am badly in need of controller for these leds

[@user-pn2ep1zk3v]

Dont understand how to connect the schematic to car +13v is "+" but what is 1.5hz "-"?

[@abdullahgungor5650]

Hi nice work there do yo have an schematic for this?

[@Sekhar_Home]

I have chevy spark... I want to add turn signal using arduino... So pls tell me how much capacitor to use at input from car turn signal.. arduino run smoothly when in bench power supply but with car turn signal it does not... It may have different frequency of turn pulse...

[@abhigyankishor4581]

dude can you link me to the bomb rewiring course you took? sick video!

[@sekiadigicel]

Any chance of doing a video of how to make the circuit board and code please? I’m so dum at these things lol

[@tomaszszczesny5337]

Hi, great Job, do you have any scheme?

[@tomaszszczesny5337]

Great Work. Do you have a scheme?

[@sneugler]

Thanks for the video, man. You ever mess with HV?

[@chems]

ZVS flyback transformers, MOT, medium sized tesla coils

[@joshcatalano5127]

I’d like to do this I have same light but have not got a clue how to it even though iv watched your video can you pay someone to do this uk based?

[@zakirmomo9578]

nice on

[@papeer3485]

This is going to my 1995's car

[@tnctechnohub]

It's awesome

[@bhz403]

chems using his cerebrum 4 once :)

[@MK1SNIP3Zz]

What does the back of the circuit board look like im building this and im stuck lol

[@cjfx4705]

Lmao “careful, careful, *BOOM* WOULD YOU LEAVE ME TF ALONE!!!!!!!!!!🤬🤬🤬🤬🤬🤬🤬 1:41

[@DASHAWNJOHN]

I was into it.....F*ing bull man

[@WisconsinA35]

How do you determine the entire resistance for an Led board and then create a circuit for it lol? Is it # of LEDs x ohm of the resistors (i.e. 10 LEDs with 5 ohm resistors would be a 50 ohm circuit?) I was usually flirting with cheerleaders during Science class lol. Never picked up on electricity :(

[@GewelReal]

SWAG

[@darkfyy]

What are you studying/ majoring right now

[@chiahow6067]

Do you sell this circuit?

[@redoxalan]

I am not clear with time controlled circuit. Can i buy online. If so what should i search

[@GoldMugu]

Sweet

[@kabircarchamp01]

Wow Sr great

[@jesse.vr6]

how's this holding up a couple months later?

[@mindhunter00789]

your genius can you make the sequential react slower

[@joshcatalano5127]

Can you just buy the led sequential strip off eBay an fit it into the rear light on this model car as I have same car

[@sekiadigicel]

Any updates on the circuit please?

[@LukSkajvoker]

ravioli ravioli, what's on my bmw-oli

[@oldgeordiegeezer3086]

So whatever happened to the "l" in solder?

[@robertfyrstling4068]

Where did you buy you’re Audi ?

[@user-pn2ep1zk3v]

And the right transistor are?

[@henkywardana4524]

Hi.. your link schematic cannot access

[@edgypone4011]

What the fuck is wrong with this channel xDDD From Unicum WoT guides, through Minecraft doors irl, to this? 10/10

[@arbremagique6253]

of course
