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