Led feedback

Hi guys I have currently got most of my controller working however the led lights are not working properly. My lights seem to either all stay on weather they are pressed or not. I would like them to be on while the action is happening and off when not. For example when I press mute the led light up then when mute is off the light goes off etc. is it possible to control the lights ? If so could someone give an example of how to do so please
