A Guide to Porch Light Safety: Leave It On or Turn It Off?

When it comes to your home's security, porch lights are critical. They guide you into your house at night and can help keep burglars away.

But porch lights have gotten a serious upgrade. Today's smart bulbs, motion-triggered fixtures, and app-controlled lighting can do a lot more than flip on and off — they can mimic your patterns, sync with your security cameras, and even respond to your voice. That's great news for your home's security. But you still need to use them strategically to get the most out of them.

Used at the right times and paired with other smart security tools, porch lights can be a genuinely effective layer of protection — whether you're home, at work, or on vacation. Here's exactly how to make that happen.

This is a good time to leave the porch light on. It alerts burglars to your presence, particularly if indoor lights are on too. The porch light also acts as a spotlight on the front door. You can easily see who’s approaching through either a window or peephole.

It helps to leave a light on for people who won’t get home until long after dark. Keeping the porch light burning helps people get to the door and unlock it safely.

When you step out for the evening, leave a porch light on. You'll worry less about the kids, and they won’t jump at strange shadows. Supplement the outdoor light with indoor ones so it looks like several people are home.

It’s wise to turn on the porch light if you have a package or Uber Eats order coming. The extra light helps the delivery person find your home, and it reminds you to grab the package before settling in for the evening.

Generally, a porch light works best when it’s coordinated with deck, garage, and indoor lights. The pairing creates the appearance that people are home and moving about.

If you’re out of town, you should turn the porch light off during the day. A constantly lit porch paints a target on your home. You should either have a neighbor turn the light on and off or invest in a light timer or smart light bulbs. The preprogrammed settings maintain the illusion that you’re home and coming and going as usual.

When it’s time for lights-out, your porch should be no exception. Turn off the porch light—the same as you would in any room in the house. Turning off a light regularly suggests that the home is in use. Plus, many porch lights available today use infrared sensors to turn on automatically if they sense motion.

It might seem like the safest move, but if you’re on your own and feeling anxious, you may not want to turn on the porch light. Burglars often stake out a property for weeks before striking. If they notice you turn on the lights more often when your partner, spouse, or roommate is away, they could decide to intrude during one of those times.

This is an instance where you may be more secure if you leave the porch light off. Intruders won’t be able to see where they’re going, and their late-night stumbling may give you a warning that they’re coming.

If you’ve invested in motion sensor lights, potential burglars will experience night vision loss, again granting you more time to call the police and turn on every light in the house.

A smart light bulb can super-power your porch without needing the buy or install an entirely new device. All you need to do is screw in the smart bulb, connect to your home Wi-Fi via the bulb's app, and your good to go.

Philips Hue is the leader when it comes to automated lighting. Its lighting system is easy to update, integrate, and synchronize. But there are cheaper options out there — some of my favorites are Wyze and Abode.

If you want to add more outdoor security than a porch light, these smart home devices are a good place to start.

Smart locks let you lock and unlock the front door remotely. With a video doorbell, you can see who’s at the front door (and talk to them) whether you’re in bed or at the office.

And a motion-activated driveway alarm alerts you when someone enters your property. Plus, if you use a smart home hub, you can create routines to make all of these security products work together—including your smart porch light.
