So thanks again! I managed to do it like you propsed with CSS and repeating-linear-gradient(). It looked quite good, but my wife was not satisfied. It looked too different from the light indicator where I am using the fa-lightbub-o in yellow or black, depending on the state. Now for the roller shutters I'm using fa-align-justify with a gradient from yellow to black depending on the position of the shutters. Now she's happy And me too, of course
