Now, you can edit these things:

(a) The base color-mine's white in this case. Change white to whatever you want in this part: 'var neonbasecolor="white"'

(b) The text's color that it changes to. Mine's blue. Go to this part: 'var neontextcolor="blue"' and change blue to your color preference.

(c) The speed it changes color (in milliseconds). Mine's at 100. Go to this section: 'var flashspeed=100 //in milliseconds' and change 100 to the speed you want.

(d) Next, the size of the text. See at the way beginning of this script it says <H2> and at the way end it says </H2>? Change H2 to match the size you want! H1 is the biggest and H8 is the smallest!

(e) And lastly, of course, to actual text at this section: 'var message="YOUR TEXT HERE. YOUR TEXT HERE. YOUR TEXT HERE."'

There you go, you have neon light text!
