You just counted it! That'd be a heckuva project i'd have to use different color led's for each area to match the lens color, and use a seperate board for each. You may be getting in over your head there.

The point I am trying to make here - is how close to a factory LED tail does your mod make our non factory LED tails? Theoretical question of course.

If everything was made to look like "everyone elses" factory, it wouldn't be custom.

They are still dual element Jose. That's how they adjust to the resistance. one element burns off a higher resistance.

Since there are no factory led tails for these models, you win either way. Bulbs without these boards, LED's with them. It's just a matter of whether or not you want them.

you'd need a dual element led to do it. Resistance does not control voltage, it controls amperage- which directly related to the voltage. You must control the led's from the voltage side rather than the amperage side. The resistance of the factory wires for the dual filament of the bulbs is completely different and unchangeable because it is built into the factory wires.
SOOO, Dual element led's or nothing at all in terms of firing them both of the same wire with different resistance. No matter how many wires you input into the board, it is still connecting to the same place, so you are tying both the wires together either way and that isn't going to work either. On the last note, by your diagram you are tying your brake light and parking light into each other = problems.
Just to be nitpicking, you have both wires labeled as 12v but with the resistance change they will not be even close to each other in voltage.

No, that would just be doing the way "you" want. There is no right or wrong, there is no standard, since there are no led tails for the model there is nothing to imitate. It's totally up to you do determine how YOU want it to look. There may be a right or wrong for "you", but there is no right or wrong, because there is no standard for the look when you are custom designing something for yourself.

Another way of looking at this is - say you see a new 3 series Bimmer side by side to a GS with your upgraded LED tail light - as soon as you look at it, does the overall quality and brightness of the 3 series OEM led look better than the GS or the same? That is what I am trying to get at. Not the design, but the overall look. The last thing I want to happen by doing this mod is to compare it to a factory LED and say to myself, what did I do this for? It looks like crap compared to that OEM LED light. (Don't take offense by the comment - it is just that a comment, nothing personal against you bro! )

I was going on the premise that resistance affects brightness. More resistance, less bright. As far as the resistance that we need to introduce, I'm talking resistors in series of the power leads of the appropriate resistances. That would have to be calculated.
No matter how many wires you input into the board, it is still connecting to the same place,
Yes, but if each lead has a different resistor inline, the brightness will differ.
On the last note, by your diagram you are tying your brake light and parking light into each other = problems.
I'm sure the right diodes can fix this. And if not, a relay sure will. It was just a quick schematic.
Just to be nitpicking, you have both wires labeled as 12v but with the resistance change they will not be even close to each other in voltage.
EXACTLY. This will vary the brightness. The +12v is just the input before the resistors.
But okay, lets pretend all this is true and it can't be done and I'm full of it.
How does this light work then? http://cgi.ebay.com/ebaymotors/ws/eB...category=42613
It's got 3 wires (ground, brake, tail) and all the LEDs light up together at *TWO* different intensity levels. I doubt a $40 pair of lights would have dual filament LEDs.
So how does this light pull it off? I see them in action all the time on the street. Busses, wreckers, government trucks... And these are designed to retrofit older vehicles so there's no modding the car's wiring. It works as is. Plug and play. So it has to be possible. Thousands of these are in use today.
Any ideas?

CleanSC,
Wouldn't relays do what you are trying to say, or is OLT saying that the LEDs are meant for a certain voltage and changing voltages doens't work. I guess the only way to really do this is to use one board, but with you can have pairs of leds and one would be the parking and the other would be the brake utilizing relays right?

Changing voltages would work, yes. Just look at your instrument clusters. You turn that dimmer switch, and what happens? They get dim.
