If you own anything with "white" LEDs, I have some bad news for you...

Or reading this on anything except an e-reader or if someone else printed it out on a printer without blue leds first.

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.
