        Luckily my device screens can all be turned off, closed, put face down and otherwise turned off when not in use. Unlike indicator lights on the routers, APs, HDDs, PCs, mice, powerbars, extension cords, radios, headphones, USB cables, ACs, microwaves etc etc etc. Either totally unnecessary to have a light in the first place, or a subtle light could do the job just as well.
