PLEASE READ THE QUESTIONS AT THE END OF THIS POST - I'D LIKE YOUR DIRECTION BEFORE I COMMIT TO ESTABLISHING A BOM
Alright, so I've chewed through the last of my 5mm Red LEDs, but we've now got a good idea of how this looks. IMHO, this turned out more aggressive than I thought it would! There's some diffuser bleed-through, so we're going to have to tackle that before I proceed. Enough, time for the pics!



BLEED-THROUGH
Obviously we can see some bleed through close-up. I changed the aperture setting to JUST get the glow of the LED to ensure you understand what you're seeing. The

QUESTION TIME
1.) Proceed with a full prototype using the breadboard? There will still be minimal bleed through. SOLUTION: CUSTOM PCB...BUT...This will jack up the cost at least $100 per pair. There will be no bleed through.
2.) For the turn, this model is a go...for the 4C guys, would you rather see 1 row on top an bottom or two? THERE WILL ONLY BE 5 ROWS FOR TURN

1. full prototype with breadboard. The bleed through isn't bad at all so far...
2. just run 1 row, i think if you try and run 2 rows they will end up to close.
3G's have all kinds of options for custom tails already, us on the 2G side have 2 choices, red/clear or red/amber that's all.

Alright, fellas...IT'S ON. I'm going to start ordering parts tomorrow night. I am going to try and source things as local as possible so we can have a completed set for test asap.
Thanks for your input, all - please chime in on the 4C turn signal option. FYI: Should this pan out, I will offer brake/running in '4' style only; ALL turn options will be available upon the buyers request.

Great work so far. 
I'd like to see it with PLCC-2 or maybe even Superflux LED's. Packing them tighter together might help with the lens distortion. A lot of guys don't like LED's behind a pillowed lens, but in my opinion, it creates a really cool effect.
Oh, and I love the rear fog idea since you can include it and let the individual determine if they want to wire it up or not.

Thanks, dude! Superflux bleed like CRAZY, I have some pics, but they're not even worth posting - it's too severe to even consider. PLCC-2, if that route were to be pursued we're talking custom etched board...and while I'm still offering that option, again, cost would be the killer 

I did a quick online quote for PCB fabrication, and it looks like it would add between 15 and 30 dollars per tail light. Less, if the order is for more than 10. That's not too bad if it saves you some time and labor.

UPDATE
All components have been ordered and are due to arrive next week. If all goes well we should have a fully functional set by Thanksgiving weekend.
FYI: There's over 600 LEDs in one pair alone, folks.

BUT, if you want the 'Deville' look, if you source the diffuser in a 3.5"x15" sheet, I'd make it work for you at the same cost of the standard set.
Here more examples of the look I'm going for

- LED Parking/Brake Light Arrays: Factory bulbs are upgraded with a dual-pattern / dual-intensity RED LED array (per tail light). In parking light mode, 215 LEDs are illuminated at low brightness. When the brakes are activated, the entire array illuminates all 273 LEDs at full brightness.
- LED Signal Light Arrays: The turn signals consist of 192 high-intensity LEDs per tail light assembly.
- Reverse Light Arrays: The reverse lights are upgraded with a high-power / high-output 21 WHITE LED array (per tail light).
- LED Signal Light Arrays: The turn signals consist of 192 high-intensity LEDs per tail light assembly.
- Reverse Light Arrays: The reverse lights are upgraded with a high-power / high-output 21 WHITE LED array (per tail light).

- Dual pattern, dual intensity design. Each tail light uses 240 LEDs during parking light mode, 320 LEDs when the brake lights are illuminated.
- Each turn signal chamber is filled with a 143 LED array.
- Reverse light bulbs are upgraded with high-output replacements.
- Factory diffuser lenses are removed and replaced with upgraded diffuser lenses offering more efficient light transmission.

UPDATE
DESIGN UPDATE
After talking things over with some people via PM, it would appear as though the running/brake will be one portion of the design and is locking in via VERSION 4.
Turn is going to be another story. There will be a prototype board options AND a PCB option available for turn - reason being is that the prototype board is not going to look as clean as a PCB for those with clean turns.

Rest assured, fine folks, the gears are still churning on my end. The first running/turn is 90% done, just need to added in resistors and test fit. I'm leaning more towards making ALL boards PCB...there will only be ONE set of prototypes produced, and probably a very, VERY limited run of boards, perhaps 5 pair total - this takes MANY, MANY hours to produce!
Been a hectic week with all of the holidays and pregnancy portraits up by Ft.Washington...and before I was ready to melt some solder core my hot water heater took a crap
I'll get some updated pics tomorrow!
