Clearing out rear signals...

I have decided that my altezza's just aren't cutting it anymore. I want to know the easiest way to clear the orange out of my rear signals. I have one site- Clearing out lights (http://www.lasalle.edu/~garofom1/writeups/4thgentails/4thgentails.html) - but that is just way to complicated for me. I was wondering if anyone else has an ieasier idea on how to do this. Any help is appriciated. Thanks!!!
