FAQ Head Unit Blue Conversion (or any color)

One question though. Which 0603's and 3mm LEDs are you using? They typically make a high output and standard for them.. .and that will make a difference on the values.
now how do you replace the clock odometer...thanks for all the info on the HU replace. I am wondering how many people have actually used resistors with their 3mm LCD LED's? some i think have said they didn't use a resistor, while others indicate they did. i am as confused as a hungry baby in a topless bar, on this one. Do i need them? don't i? planning to do this mod as soon as i get some time. Thanks.
Ordering this afternoon... what is the best source people are finding for the 0603's? So far mousers super bright 0603's for about a buck are the best I have found. Just thought I would check before ordering them.
I had purchasedsome 3mm LEDS for my cupholders and still had a few left. I purchased these with the resistor already attached and with heat shrink tubing over the legs. I removed the heat shrink tubing last evening and found a 430 ohm resistor.
I used two of these for the LCD in my xA conversion and they seem to be equivolent to the light output of the original LCD light bulbs.
Not sure if this info will assist anyone, but I thought I'd throw it out there.
BTW I have a variety of new resistors in numerous values in case anyone need some.

This is who i went through for mine and it was a hell of a deal......considering they are coming from Hong Kong it was here quick too
http://stores.ebay.com/LED-LAMP
Lots of colors and quantities.... i bought a 50 pack for $11.99 plus $2.50 shipping
couldnt beat it!!!!!
that price is really cheap... mouser.com ones are backordered now... I don't know if I should buy some on ebay and replace all of them or wait for mouser.com to get those back...
DoggyStyle, so using 430 resistors work? if yes, i will go buy some from Radio Shack or Fry's to do them... hopefully the extras don't blow when i try to get them to work again

The gauge and center console LEDs we use are capable of around 300 mcd. However, with the amount of current we are allowing I would say we are somewhere around 200 or less. The buttons on the stereo are so small and dim looking compared to the rest of the dash I dont think we would be doing bad with the lower rated ones. For those who have used the ones off of ebay, how bright do they look compared to the gauges?
just another question engifineer, is there anyways to replace the LEDs for key insertion? factory color is white... it's cool to me already, but if it's blue, gonna be tight!
i would also like to know about changing the other lights, AC Control section, and Clock / Odometer. anyone ever try and do these? i feel bad asking other people to screw up their electronics before i do this mod to mine...oh well, i'm over it.
thanks for being the guinea pigs guys...

Those are for the tC. On the console one look through all of my posts, I did add an update regarding the clock portion. I need to clean up that tech article soon.
Here are pics of how they turn out once the center console circuit mod is performed:

I have not thought of the key light yet... that may be a cool one to look into
