In the last few years I have purchased a pressure cooker and an air fryer. They both waste electricity by having an off light. Furthermore they act like red nightlights and my kitchen has an eerie red glow at night. What is the actual purpose for off lights besides to waste electricity?
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.
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
Because corporations benefit from keeping the working class from getting good sleep.
For soundbars at least, the off light is there because there shouldn’t be any lights on while it’s being used so as not to distract the person watching tv. So the only way to know if the device is off is to have a light on.
Maybe just have it exclaim “I’m off!” every five minutes, no need for an extra LED then.
