Create the LED bar movieclip

Create a new movieclip symbol (let's call it mv_LEDbar) with 2 layers, name the upper layer LED mask and lower layer LED color. Drag an instance of mv_bar into the upper layer, position it at x=0, y=50.

Add the following movieclip action to the instance of mv_bar.

onClipEvent (enterFrame) {
indicator = Math.round(Math.random() * 100);
if (indicator <%gt%> 55 && this._y <%gt%> 5) {
        this._y -= 10;
        } else if (indicator <%lt%> 45 && this._y <%lt%> 55) {
        this._y += 10;
        }
        }
