An empty, consistently dark home for many nights in a row quietly advertises that nobody is around. A simple timer plug connected to a lamp can turn it on and off at set times, making it look like someone is inside in the evenings.
You plug a floor lamp or table lamp into the timer, set it to turn on at dusk and off late at night. From outside, it appears that normal patterns are happening – light comes on, later it goes off. It’s not a guarantee of safety, but it reduces the obvious “totally empty” signal.
This is especially handy during holidays or work trips. Paired with neighbours keeping an eye and mail not piling up, it helps your home blend into the usual building rhythm.
