There are more courtesy lights in my little place than the law should allow...smoke alarm light, surge protector lights, (3) modem lights, and clock on the cable box. That doesn’t include the ambient light from the security lights both in front of and in back of my apartment and my own porch light.
Lucky me, I’ve learned to sleep through them all.
My work laptop’s power supply has a stupid blue LED inside the plug to the laptop that illuminates a ring on the plug body. It gives off so much light it’s kept me awake at night in hotels.
