Off lights let you know if it's broken. If it's on, it's obviously working. If it's off and the light is on, it's getting power. If it's off and plugged in, but not displaying the light - that indicates it's broken or not getting power.

That makes no sense to me. Why not have an on light instead? If the light is on, and the device is operating as expected, that's good. If the light is off then it has no power or it's broken. If the light is on and nothing is happening, it's broken.
If the light is going to be annoying when the device is on, then turn it off after a few seconds.
Seems like a solution in search of a problem.
Seems reasonable on something dangerous like a toaster oven or pressure cooker that you obviously wouldn't want to leave on and unattended. These lights use almost no power at all.
You could also just try turning it on to see if it has power. I don't see how the light is actually useful for this.
The off light reminds me to unplug the device when I don't need to use it.
The ultra tiny amount of electricity is... Well you probably would never notice it on your bill.
But yeah it can be annoying having it there. I guess the purpose is to tell you that it has power available if you need it
Yes those small LED indicator lights use around 10-20mA of current at like 3V which is only 0.06W of power.
Just unplug them? Most appliances still draw some electricity (i.e. phantom load) when turned off.
get a Samsung appliance – they like to use ultra-bright BLINKING blue LEDs for sleep mode
I have a monitor that does that (but in white). It's in my bedroom. I had to use electrical tape like another commenter here mentioned - I left a tiny hole in the tape so I can see a faint light up close, but it's not making the room blink at night now.
I'm never buying another Samsung monitor.
I can literally hear it blinking on and off at night, so I need to manually turn it off.
Damn my perfect hearing.
I figured the purpose was to warn us that these devices have been left plugged in while not in use, which is not advisable because they can become a fire hazard.
I visited my parents last weekend. They have s printer which has a wave light signal in standby - gradually switching from off to strong light and back. What my parents probably never noticed was the high pitch loud screech which followed the light. I guess the pitch was too high for my parents to hear, but not for me. So whoever designed that can go fuck themselves.
I cover lights like this with black electrical tape so they don't sear my eyes at night.
Just to see the blue light creep out elsewhere in the cheap plastic box...
It should be fucking illegal to have lights on when the whatever if off.
Because corporations benefit from keeping the working class from getting good sleep.
Knew it was corporations conspiring to keep us from a good night's sleep
