here's what mine look like, blue also. the pic is a little blurry but you can see they are blue now.

Looks sweet guys! I want to do that mod to my car as soon as I can dig up enough money to cover the cost of leds.

for me, it was a walk in the park to do. there are some modifications that need to be done to the led's themselves as well as the switches...

Any idea on where to get 5V 3mm 180 degree LED's? I stopped by the local radio shack, but no luck. If i understand correclty, you can get rid of the resistor if you use a 5V led. What if you use a lower voltage led? How do you know what kind of resistor to use? Is there a formula for this? Thanks!!

I haven't found any, don't need 180 degree either like I thought and so I just used the 5mm ones. Nope, have to have the resistor, except for on the master window switch on the drivers side, they are done in series so as long as all 4 led's voltage add up to be more than 13v then you don't need a resistor on that one at least, but if you use 5v led's in there, that's 20V so they might not be that bright as they are having to share only 13 and need 20. As for figuring a resistor, you do it this way, the resistance=(Voltage-forward voltage of led)times 1000, divided by the mA of the led. R=(V-vf)*1000/mA

OK, thanks for the help. Just to clarify, the formula you gave is for figuring out what resistance resistor you need in the circuit, or for figuring out the resistance of the LED? If it is for figuring out the resistance of the LED, what should the total resistance be? Thanks again!

any chance any of you guys kept a rough list of what led's you used/ replaced, and the resitances they needed? i could put together a bunch of radioshack catalog numbers and we could make a little howto for those that are interested in doing this later.

Take the voltage of the LED and subtract that from 12V. Then divide that by the forward current rating of the LED. That gives you the resistor required.
E.g. for a 2V LED with forward current of 20mA, the required resistance is (12-2)/0.02 = 500ohm.

Chris H. Had a great mod for changing your clock to a blue color you should check into that also
