Does anyone know how I can do this to my gauges? And is it very difficult to do by myself?

 

not easy unless you feel very confident with your soldering skills, and if you f*uck it up, be prepared to spend a few hundo to fix your mess up.

 

Yes, very hard time consuming process. In a quick summary, you have to pull the dash out, get the whole tach and speedo out, and open up the back. Once in there, you have to unsolder the old OEM LED's, and then re-solder new (different colored) LED's. Doesn't seem too hard...but it is, because you have to check each LED before you do the next, to make sure it works, and that means putting it back into the car. Oh, and here is the kicker: There are like 147 LED's.

Doesn't seem that difficult to me:
1. Take picture
2. Open picture in photoshop
3. Select color replacement tool
4. Paint in new color
5. Post to web

Where's the hard part?
