if i get these done and working would any one want to buy them?

buy WHAT,a completed LED tail, or LED's themselves?

i am going to make a set of tails like John Piparo but add back up lights in to it too. dose this look right???

you might want to run the LED's in parallel(sp) instead of in series. I've found that more than 3 LED's in series can cause some problems depending on the LED

Meabe those project become popular...
im also making one, but i read alot about it, before
making it...

eumm Grimor,
never heard of this,
but Larry,
how will you do for making your led
dim for your tail light, when your not braking ?

i want to make these too but i dont really have the time now to learn about LED wiring and such.

on a side note, listening to john would be in your anyones best interest. that guy knows a lot about this stuff

Very awesome project... love to see how it'll look with the Cavy. Maybe tinted glass with the LED's?

Larry, I have a piece of "breaking news"

The 12v voltage regulators, don't use em. WIth the car off, lights on, they will act as a resistor and the LED's will be too dim to see. I ran a test with my amber plate and now have to rewire it. Same deal with the reds.

Run the input voltage as 13.8 on the wizard to get the correct resistors, just to be on the safe side.

In my tails, I only used 3 rows of 6 red LEDs, the bottom row is for parking, and the top two are for brake/blink, and I threw in 3 white LEDs in the corners for reverse. And I was told from friends following behind me that if, anything, they were a bit too bright.





What I would suggest to you if you plan on doing that, is to simply figure out a way to dispurse the light to cover the entire area that you want, rather than filling in the entire area with LEDs. The way you have them plotted out now will just be too much work, and probably turn out too bright, and look like city bus tail lights.



are the reverse lights bright enough to be able to see from the leds????????? but these look bad ass... i am thinking about doing somthing like this, but a different "pattern" i guess you would call it. but yes, if somone could email me some tips, that would be great. thanks

i think i will have to agree........ i have a feeling that if they are run in series, they start dimming by the end....

i also beleive that you would need to calculate the resistor for one, the use the same ressitor for all of them parallely.....

If i'm wrong, please correct me............

what are the specs on the led's?

ex:
1.7 volt <--- volts it uses
20mA <--- amps
800mcd <--- brigtness (important, especially if being used in your application)

i used 1/2 watt, 560 Ohm, 5% tolerance resistor, and works beutifully.
i believe the formula goes like this

[ supply volts - used volts ] / amps
in my case it goes like this

(12 V - 2 V) / 20mA = Ohm's
(12 - 2 ) / .02 = 500
case and point why i used a 560 ohm resistor.

you can go up in the resistor Ohm number, but not down.

Hope this helps a bit on the LED confusion....

12,000mcd reds?! Too bright man, mine are 6,000 and they are a little too bright.

i am going to test them now and if there to bright i'll just buy different ones




Re: Led tails
Thursday, October 13, 2005 9:13 PM
well i tested them theres no way they can be 12,000




Re: Led tails
Thursday, October 13, 2005 9:28 PM
Larry..can you shoot me a PM or email to let me know what kinda LEDs to get..i was gonna get the 5mm, but if they are gonna be to bright maybe i can do a diff. size..thanks in advance
