or a simple solution would be to have a movie clip that has you light glowing regular and dim and use a random to switch back and forth
say you lamp is a movie clip called “lamp” with a stop(); command on it’s first frame

function flicker(e:Event)
{
var ranFlick:int = random();
if (ranFlick > .8){
lamp.gotoAndPlay(“dim”);
}
}

get the idea
