That bright LED's became so cheap to allow putting them everywhere certainly had downsides. There are many devices now where I have to tape over to enjoy a dark sleeping place.
This is my only complaint about the Bose QuietComfort Ultras. Nearly $400 headphones and they have an LED that glows while charging so I can’t charge them in my room at night unless I throw a shirt or something over them.
Makes me wonder if e-ink could solve this. A red dot that's only visible in daytime, when you want it to be.
Back when red LEDs were the new cheap lighting option everything was great: red doesn't affect noght vision as much and at least for me it doesn't seem to prevent sleeping on the same way that the bright white LEDs do.
