any one tried it?

blueneo03 · Post by **blueneo03** » Mon Apr 27, 2009 8:18 pm

has anyone tried to make the 3rd brake light into a L.E.D. brake light.. not like just replace the bulb to an led one, but like actually making it into a true led like on some of the new caddys and such

Pablodragon · Post by **Pablodragon** » Mon Apr 27, 2009 8:32 pm

I did this... have posted it before...

all I did was hot glue a L.E.D. alarm scanner inside the stock red lens and hook all the power wires up to the brake light circut that was there.

some say it's illegal, but I've had it for years and have cops behind me day and night without getting pulled over.

Yep, its been done. Do a search.

somewhere is a step by step how-to
(could be that it was in srtforums.com ...)

Yea if anyone finds it let me know. If mot I will make one up as I was gonna try to make one in the next couple of weeks.

i cant find a how to... i was lookin on srt forums and on here and i cant find any how to's just like sellin them and showin finished ones... i want to make my own and save money... buz i can get 30 leds and 30 resistors for 15$ and do it myself .. i just need a little help with how to wire it up...

I have an LED board, with turn signals in the board. I'm special.

If you can get ahold of night hawk I heard he has some electrical boards that he used to make his. Maybe we could get em. Ive had no luck with pm's. Let me know

He has been really busy lately and doesn't have much time for the internet.

yeah, nitehawk sold some pretty cool l.e.d. stuff.

man I'm waiting until someone post some pics of this.

Caraudioholic24 · Post by **Caraudioholic24** » Wed Apr 29, 2009 2:01 am

If I can get around to it in the next couple of weeks I will show everyone my design. If you guys like it I will make them for everyone!!! Just may take a little bit.

blueneo03 · Post by **blueneo03** » Wed Apr 29, 2009 2:58 am

that would be awesome.. ive been lookin everywhere and i cant find out how to wire it....

ooh! sounds good

Well mine will be a plug in type. Only gonna do two rows of red leds. Nothing fancy just want it to match the taillamps

I'd be ok with just one row, I actually think it looks better than 2 rows, but it's not as bright.

blueneo03 · Post by **blueneo03** » Wed Apr 29, 2009 1:14 pm

i would only do that too... i dont need blinkers or that fancy stuff.. just an led brake light.. and i need to know how to wire it and all...

Caraudioholic24 · Post by **Caraudioholic24** » Wed Apr 29, 2009 1:38 pm

Yea Im gonna experiment and maybe put a poll up to see which ones you guys like. I am going to use a smoked lens so it should blend nicely

Are you jokin?
I just entered "breaklight" into the boardsearch and it was the 3rd topic.

oh... thanks,... i guess i was just doin the wrong searches... i was typing in 3rd break light and led 3rd and other things like that.. too specific i guess... but thanks man..but that didnt show what i was looking for... i need the wiring part.. i can do all that type stuff no problem.. i just need to know how to wire the board and leds

Jenni · Post by **Jenni** » Thu Apr 30, 2009 5:19 pm

4 in a row and the rows parallel...

blueneo03 · Post by **blueneo03** » Thu Apr 30, 2009 5:48 pm

ya but what about resistors and such.. and like type of board... i think just regular pc board.. but i dont know about wiring the resistors you ca do one per led but other than that what can u do?

Jenni · Post by **Jenni** » Thu Apr 30, 2009 6:06 pm

If you solder 4 in a row you don't need resistors. It's simple math - 12V : 4 = 3V. And now look how much the LEDs need. I guess 3V is okay...
The board? Just take standard board for selfwiring. (Whatever you call that...):

blueneo03 · Post by **blueneo03** » Thu Apr 30, 2009 6:10 pm

alright. thanks man.. i can wire.. but i dont really know resistors and such... but you wouldnt need any resistors? or 1 every 4?

Jenni · Post by **Jenni** » Thu Apr 30, 2009 6:19 pm

it's like i said. math. you only need resistors if the voltage is not the same. Example: The LED needs 3 V and you have 12 V. Then you must know the needed current to calculate the resistor.
If you only wanna install 1 LED (like in switches) you need a resistor (for blue LEDs = 420 Ohm). But for reds it's different, they need lower voltage...
But if you connect them in row - the voltage must be added - 4x3 = 12 V...

blueneo03 · Post by **blueneo03** » Thu Apr 30, 2009 6:21 pm

alright you have been a great help thanks man

Jenni · Post by **Jenni** » Thu Apr 30, 2009 6:29 pm

no problem. have fun with trying it!

PS: Made my domelight the same way:

Caraudioholic24 · Post by **Caraudioholic24** » Fri May 01, 2009 2:42 am

Yea but a vehicle with the engine running puts out a max of 14.5 volts. If you wanna try to use the board I recommend using inlie resistors. Depending on the size of the led and the color they use different ohms.

On another note the 3rd brake light will only be on for a min at a time. I dont see the voltage spike being a problem. If you wanna try it go for it.

Jenni · Post by **Jenni** » Fri May 01, 2009 2:26 pm

with 14.5V you have 3.6V / LED - should be no problem...
