Need a blinking light script

I am building an item like a computer and I want a script that will make some of the buttons blink on and off. I need the script to be full perm so I can change the time delay between the blinks on various buttons, Anyone have a script like this?

Here you go this should do what you want

........................... copy everything below this line .............................

// red = <1,0,0>;
// green = <0,1,0>;
// white = <1,1,1>;
// black = <0,0,0>;
// gold = <0.5,0.5,0>;
// blue = <0,0,1>;
// orange = <1,0.5,0>;
// yellow = <1,1,0>;
// brown = <0.5,0.25,0>;
// pink = <1,0.5,0.5>;
// purple = <0.2,0,0.2>;
// lime = <0.5,1,0>;
// sky = <0.5,1,1>;
// lavander = <0.2,0.2,0.4>;
// you can use any of the colour codes above here in the colour vectors below .

vector COLOR_1 = <1,1,0>; // yellow used
vector COLOR_2 = <1,0,0>; // red used

integer USE_COLOR_1;

default {
state_entry() {
USE_COLOR_1 = FALSE;
llSetTimerEvent( 2.0);// change blink speed here.. it's set to blink every 2 seconds
}

timer() {
if (USE_COLOR_1)
llSetColor( COLOR_1, ALL_SIDES );
else
llSetColor( COLOR_2, ALL_SIDES );

USE_COLOR_1 = !USE_COLOR_1;
}
}

Blink how, as in full Birght, not fullbright? Light, not light? or color change like the script above?

I suppose light, like RL computers.

also .. if your doing it on like a keyboard you might try and use an animation textures.. instead of a seperate prim for each light..
