So this leads me back to the beginning of the problem.... figuring out what voltage and amps the current LED's are so I can replace them. Any suggestions? (google didnt turn up much useful info). Anyone got an electrical engineering degree in here lol
^ 1.91v (Bright setting)
.63v (Dim setting)
so yeah I not only have no clue what voltage but do not know the amps either. To measure amps you have to disconnect ONE of the leads from the LED's... I haven't gotten that far yet but I'm worried that the amp draw will also be modified by the PWM

I'm just eyeballing here, but it looks as though these may be in line to what you're looking for...

But I have no idea what size those actually are. I can tell you that I tried to do something similar, though these LEDs were considerably smaller. This was with the PFC Commander and it was virtually impossible. I had a friend who worked with Northrop Grumman at the time have their electronics guys take a look and said they couldn't do it without destroying the thing.
However, this seems a lot easier as they are, relatively speaking, a lot larger than the other ones. And based on what you saw for voltage, the first set listed should work fine. The question is whether the color is exactly what you want...and they're the right size.
And thanks in advance for said package.

You don't need to worry about the amperage. Any LED will work, but you just need to know the correct voltage as not to over or under drive whichever LED you get. I think it will provide enough current to not be an issue.

ebay to the rescue 30× OSRAM LOT676 ORANGE LED 180~224 mcd 120° PLCC-2 SMD http://cgi.ebay.com/30-OSRAM-LOT676-...item3efdcae233
and here's a handy color chart. http://www.oksolar.com/abc/led_color_chart.htm I think plain ol orange should do

Here is a link to the OSRAM product catalogue in case you need it:
http://catalog.osram-os.com/catalogu...t=showBookmark
I think you have the correct ones for your app but there are much brighter ones if needed.

I got the LED's in today... i swapped one out and no dice 
it wont light up and takes down the LED next to it. Put it back in and everything is fine, so basically I'm back to square 1. The form factor one these LED's are IDENTICAL to the ones in the gauge which is the most puzzling part. Either the voltage is wrong or I just have a bum batch of LED's... but the voltage of the LED's in the unit now are were damn close to what I ordered (though its not real voltage, its PWM so the multimeter kinda sees an average). Maybe the LED's I ordered can't be pulsed?? I have no idea... anyone here an electrical engineer?

Ok, so I'm very confused now. I decided to test the LED's individually to see if they were bad. They worked, so I then tested one of the LED's from the gauge. To my surprise the anode and cathode are SWITCHED on the osram LED's. Very very odd, and the are identical in size, shape, color, as well as the little tabbed corner which is supposed to denote which side is the anode. These LED's are slightly less dim than what is currently in the gauge now. I'm going to swap a few out and take a picture to show the difference, and then do the rest of the LED's and put the face on to get an idea of how it will look.

Done. I want to send a big thanks to Christian (Railgun) for helping me find the LED's as I looked for a long time and could not get a good lead on them !
So the LED's are backwards from the ones in the STRI gauge (tabbed corner is reversed) but other than that a pretty simple install if you have a steady hand and a sharp tipped soldering iron and very very thin solder.
The innovate gauge was much much easier. That one just took an orange sharpie on all faces of the clear insert, and another coat on the back of the gauge face itself. It matches identially in color to the STRI now. So all i have left to do is the other three STRI gauges .
So that being said, for all those who are totally **** retentive about their FD's... enjoy.

Nice! And you're welcome! Though I didn't do too much. 
That turned out great. Glad you were able to find ones you liked.
You think those are tiny? These are the ones on the PFC Commander.
I still have the samples around here somewhere I think. They are impossibly small. I don't even know where to begin with getting those removed and re-soldered on there without destroying everything. I think they're more epoxied on as opposed to soldered. I just don't know where to start.
