The blue LED was supposed to be impossible—until a young engineer proposed a moonshot idea.

It seems that the blue led is picked by many manufacturers now for its coolness factor. There are so many appliances people have in sleeping areas with blue lights glaring and disturbing sleep

I carry a bit of gaffer's tape everywhere for those little obnoxious blue bastards.

It’s such a big problem that there’s literally LED dimming tape on the market. It’s semi-transparent tape that you stick over the blue LEDs, to knock them down to a more reasonable brightness. It’s akin to putting sunglasses on your appliances.

I just layer on masking tape until it's dim enough, usually 2 layers

The last like 3 computer cases have had blue power leds. They often are brighter than night lights. I have gotten to the point where I only connect the power button as the leds are so bright and the number of times I’ve inadvertently hit the reset button.

I made a hobby PCB with indicator LEDs and I have to admit that was the reason for my choice. The surface mount frosted "milky" ones look especially great, where they have the diffusion layer so it's not a harsh glare.
