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.

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.

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.
