LED 3rd brake

LED 3rd brake (Built not bought)

What happens when your bored with 500+ 15000mcd LED's, A few hundred sorted resisters, and a spare 3rd brake light setup?

So the setup was as followed.....
three rows of 3 of 3 LED's, all are going to be set up in series then in parallel.
this means that if one LED happens to go bad, the rest will still be working, while all of them will be supplied by the same power source.

What LED's and Resisters did I use?

24 red 15000mcd 5mm LED's
with the correct math you can get the right resistor size for any combo.
Current combo was one resistor per LED.

Here is the math.....

R = (12.0V - 2.3V) / .02 A
R= 485 Ohms

This we need to round off to the closest 5% value.
so I used a 560ohm resistor since its a popular and its a easy to get resistor,
and it will also insure a long life for the LED it will be attached to.

Here is one side finished

Here it is completely finished and wired up for plug and play.

Here is a closer look at all 24 LED's, 9 on each side and 6 where the 914 light bulb once was. The 6 LED setup is also a series parallel setup.
this one I was suppose to use a 390ohm resistor, but I just used the same 560ohm to bring the brightness of the lights down since I would have 2 LED's per 1 resister.

And now the finished product.

Haha, awesome. Love seeing people do electrical stuff like this.

And now I have another one, lol
this one has 14 LED's on each side plus six in the center.
that 34 really bright LED's

Should take a night picture

24 LED's at night

and 34 LED's at night

how much to buy one of those off ya? especially if you do the white bed lights too! :

 

[Northern]

White bed lights as in convert them into brake lights? Or just add some bright white LED's so they work the way it was meant to be?

Yes. That would be awesome. Haha.

 

[Northern]

Ummmm!!!!!!! still didnt help....

Red LED's in the cargo lights and convert then to turn on as a brake light?
or Bright white LED's and leave them as Cargo lights?

Ive got a better design in mind, so don't go falling in love with these yet.

I have a ton of the clear/red 15000mcd lED's
but Im running low on the clear/white 20000mcd LEDs but I placed an order for 5000 more today

I would buy one depending on price if you did it with bright white LEDs. I have LED bulbs in mine but the brake light is always on really dim when I drive and then gets bright when I hit the brakes.

Whoops, I forgot to delete part of it haha. The white led's as the cargo light, and as a reverse light, if they dont already do that haha. Strange that I've never noticed if those come on while in reverse...

And what's this better design and what's a ballpark estimate for us buyers?

@ daniel3507

Sounds as if you have a short, or one of the resistors is toast and its creating feed back.
but you still shouldn't have any power running to the brake lights unless you have a faulty brake light switch.

@ mdn14 & Killj0y

The better design will create a more even pattern of light, a little brighter then my 34, and more compact in design, but still a Plug n Play setup.
Ill end up using the 20Kmcd's whites on PCB's for the whole thing.
As for price, if you exchange the light so I can use your old one for another.
Exchanged: 30, w/o: 40 and of course plus shipping... USPS flat rate....
If you have a custom or tinted 3rd light ship it to me, Ill convert it and ship it back to you.

It sound like a lot but if you check other LED 3rd brake lights you have 3,6, or 10 LED's for the same price and they are only the 8kmcd LED's.

Mine will be WAY brighter and with a BUNCH more LED's.

Sweet! That's sick.

Could I also send my tail lights and have you do those in some sorta epic setup?

 

[Northern]

Sure,
What type of setup are you looking to have done?
draw it out and send me a pic in my inbox or email.

 

[mdn14]

Idk. Just some wicked setup. I'm not the most creative person...
