An empty house gives itself away. The same lamp on at the same time every night, a pile of flyers on the porch and a dark house in an otherwise lit street all say that nobody is home. The cheapest fix is to make the house look lived in, and there are four ways to do it, from a $10 dial timer to a smart bulb system. This guide compares them, explains how to make the lighting look natural, and covers the other signs of an empty house that lights alone cannot hide.

Why an empty-looking house is a target

People who break into homes tend to look for easy, low-risk opportunities. One of the simplest ways to judge risk is to see whether anyone is home. They look for signs such as dark windows at night, mail piling up, newspapers on the driveway, an overgrown lawn and no sign of life for days. A house that looks occupied is a bigger gamble, so many will simply move on to one that does not.

Making your house look occupied will not stop a determined burglar, but it removes a signal that tells them it is easy. It also costs very little, which makes it a good first step before a trip. Our home security audit includes a section on habits and travel that goes with this guide.

What makes lighting look real

It is not enough to put a light on a timer. A convincing pattern follows how people actually live. Keep these principles in mind, whichever product you choose.

• Vary the times. People do not turn lights on at exactly 6:00 every evening. A pattern that never changes looks automated, especially to someone who watches for several days.
• Use more than one room. Lights that move from a living room to a bedroom to a bathroom suggest a person moving through the house.
• Match your real habits. If your living room is usually lit until 11 p.m. and the bedroom after that, copy it.
• Include a bit of daytime. A radio or a light in a room that is always lit during the day can help on a long trip, but only if it does not look odd from outside.
• Think about what can be seen. Lights in rooms with a street view matter. Lights in a back bedroom nobody sees do not.
• Do not leave a light on all day. A lamp burning at noon in the sun looks like a mistake.

Four ways to automate your lights

1. The mechanical plug-in timer

A mechanical timer has a dial with pins or tabs that set when the outlet turns on and off. It plugs between the wall and a lamp, needs no app, no Wi-Fi and no account, and cannot be hacked, because it is not connected to anything. It is the cheapest and most reliable option.

Its weakness is that it repeats the same schedule every day, so the pattern looks mechanical on a long trip. It also does not let you check or change anything remotely. For a weekend away, that does not matter. For two weeks, it might.

2. The smart plug

A smart plug connects to your Wi-Fi, and you control it from an app. Many models have an "away" mode that randomizes the on and off times within a window, which is exactly the variation that makes a house look occupied. You can also turn lights on from anywhere, which helps if you come home late or change your plans.

The costs are small: it needs a 2.4 GHz Wi-Fi connection and an app, and a lamp stays off if the plug loses its connection. It is our pick for most people, because it solves the main weakness of the dial timer for only a few dollars more.

3. The timer bulb

A timer bulb has a clock built in, so you can screw it into any lamp or fixture. There is no outlet adapter and no Wi-Fi to configure. The schedule is set by a physical switch, and it keeps working during an internet outage.

The catch is that the timer resets when you turn the wall switch off, so you need to set it again each day, and it offers fewer scheduling options than a smart plug. It suits a simple porch or hallway light, or a lamp where a plug-in timer would not fit.

4. The smart bulb kit

Smart bulbs replace the bulbs in your lamps and let you build detailed routines across several rooms. You can set one room to dim as another comes on, or have the bedroom light up at a believable hour. This is the most realistic way to imitate a person, and it works with common voice assistants and smart-home apps.

It is also the most expensive option, and a kit needs its hub, or bridge, for full scheduling. It is worth it if you travel often or already use smart-home gear. If you only go away a few times a year, a smart plug is better value.

A simple setup plan

1. Pick two or three lights in rooms with a view from the street or yard, such as the living room, the kitchen and a bedroom.
2. Set different schedules. Start the living room lamp at dusk, run it late, and bring on the bedroom later.
3. Test it before you leave. Walk outside after dark and check what the house looks like from the street.
4. Add the porch light. A dusk-to-dawn bulb takes care of it automatically. See our guide on motion vs. dusk-to-dawn lighting.
5. Have a backup. Tell a neighbor or friend that you will be away, so someone can notice if a light stays on or off.

The other signs of an empty house

Light is only one signal. The following matter as much, and most cost nothing.

• Mail and packages. Ask a neighbor to collect them, or put a hold on your mail with the postal service. Reschedule deliveries to arrive after you return.
• Flyers and newspapers. Pause delivery, or have someone pick them up.
• The lawn and the snow. Arrange for someone to mow or shovel, so the house looks maintained.
• Garbage cans. Ask a neighbor to roll them to the curb and back.
• Your cars. A driveway that is always empty is a signal. A neighbor can park a car there from time to time.
• Social media. Do not post that you are away while you are away. Share your photos after you return.
• Voicemail and the garage door. Close the garage, and do not announce your travel on your voicemail greeting.
• Hidden keys. Take the spare key out of the flowerpot before you leave. Our deadbolt guide covers rekeying and key control.

Which should you buy?

Common mistakes to avoid

• Using one light on a fixed schedule. It is the easiest pattern to spot.
• Lighting rooms nobody can see. Think about the view from outside.
• Leaving lights on 24 hours a day. It looks wrong and wastes power.
• Forgetting Wi-Fi limits. Smart plugs stop working if the router goes down, so keep a mechanical timer on your most important lamp.
• Letting mail pile up. A full mailbox cancels the effect of your lighting.
• Announcing your trip online. Wait until you are home.
