The following things in my house have some kind of light on all the time whether they are in use or not:
- Microwave
- Camera battery charger
- Laptop
- Phone
- Cell phone
- Baby monitor (transmitter and receiver)
- Smoke detector (x3)
- Alarm clock
- Cable modem
- Wireless router
- Coffee Maker!?
There is also a street light about twenty feet from my front step.
Camera charger? Just unplug it. If there is no battery in it, is has no reason to be plugged.
I had to blacken out the green light on my Apple airport express to get our bedroom dark at night. Also – my old powerbook has a fun heartbeat glow when it is asleep, but it really lights up a dark bedroom, ironically making it harder for others to sleep.
What about your cell phone charger? My cellphone charger (blackberry) has a small light on it. I try to unplug it when I am not charging my phone, but sometimes I forget.
