Has your motion sensor light stopped working, or is it stuck in the “on” or “off” position? A motion detector light is sensitive to power surges and blinks and sometimes will not work correctly following an electrical episode. While you may think the fixture is broken, many times, it often just requires a reset. Taking a few minutes to troubleshoot the motion sensor light can save you a lot of hassle and money and requires no special tools or skills.
If you find your outdoor sensor light not working, get it fixed right away by calling your local Mr. Electric®. Not sure if you need repairs just yet? Read on to learn how to reset a motion sensor light that stays on all the time.
How to Reset a Motion Sensor Light
Is it possible to get your motion sensor light "unstuck" and working optimally again? Before you shell out the cash for a new light, follow these troubleshooting tips to see if you can get your light working.
Steps to reset a motion sensor light:
- Turn off the fixture's circuit breaker for at least 30 seconds.
- If the fixture has a light switch, turn the switch on for 2 seconds, then off for 2 seconds, and then back on.
- If the fixture has a light switch, quickly switch it on and off four or five times or until the light stays on.
- Once the light remains on, turn the switch off for five seconds, then turn it back on.
- Replace the light bulbs in the fixture to ensure it isn't a bad bulb issue.
Once you've completed these steps, you will know if you need a motion sensor light reset or if your best plan of action is to update your outdoor lighting. No matter what your motion sensor light needs, you can rely on your local Mr. Electric team to help.
What Causes Issues with Motion Sensor Lights?
Motion sensors are sensitive pieces of equipment, making them prone to minor issues, so it's not surprising your motion light stays on or off at inappropriate times. Some of the most common causes of issues with motion sensor lights include:
- Dust buildup: Dust and dirt can gather in your motion sensor light’s sensors, rendering motion detection impossible. Sensors can be gently cleaned with a rag or compressed air.
- Blackouts: Power surges and blackouts can impact the sensor settings. A reset will usually fix this problem.
- Burnt-out bulbs: Check if your light bulb burned out before calling for repairs or replacing your lights.
When Should You Reset a Motion Sensor Light?
If your motion sensor gets stuck in either the “on” or “off” position and no longer gets triggered in these scenarios, try a motion sensor light reset:
- Large moving objects like people or vehicles don't trigger the light.
- The light stays on for long periods of time or permanently, rather than turning off shortly after the movement has stopped.
- The light seems less sensitive than usual and does not consistently detect motion.
When a Motion Sensor Light Reset Might Not Be Enough
Resetting your motion sensor light is a solid first move, but it's not a cure-all. If your light keeps acting up, even after a reset, there may be a deeper issue that needs attention. Here's what a basic reset won't solve:
- Faulty wiring: Loose connections, corroded terminals, and outdated wiring can keep your motion light stuck on and even prevent it from working at all.
- Defective sensor or light fixture: Over time, sensors can wear out or the internal components can fail.
- Incorrect installation: If the light was never wired or mounted properly, it might flicker, stay on constantly, or not respond to motion.
- Damaged components from power surges or weather: Storms, water exposure, and power spikes can fry internal parts, even if the outside looks fine.
- Overloaded circuit or incompatible switch: Some motion lights aren't compatible with dimmers or smart switches. Others may trip the breaker if they're sharing a circuit with too many high-draw devices.
If you've already tried to reset your motion light and it isn't working properly, it's time to call in a trusted service professional. Your local Mr. Electric can safely track down the cause of your problem and recommend next steps – whether that’s fixing it or replacing your motion sensor light.
How a Pro Can Save You Time and Guesswork
If you've tried the reset, ruled out a burnt-out bulb, and your motion sensor light is still not working, it might be time to step away from the ladder. Mr. Electric has the experience to pinpoint exactly what's going wrong.
A trained and experienced service professional can:
- Test the wiring to make sure your light is getting power
- Inspect the sensor for internal damage that's easy to miss from the outside
- Verify the circuit isn't overloaded or interfering with the light's function
- Check compatibility with any smart switches, dimmers, or timers on the line
- Rule out hidden issues like moisture damage, poor connections, and voltage irregularities
Most importantly, an electrician can ensure that your motion light is working safely. Sometimes, the problem isn't the light itself. It's the system behind it.

FAQs About Motion Sensor Lights
The safety of you, your family, and home are the top priority of every Mr. Electric service professional. Our safety-first commitment to solving your electrical issues includes a meticulous attention to detail on every job. Our commitment also includes using our years of experience to answer your questions. Below are answers to some of the most frequently asked questions about motion sensor lights.
Can cold weather affect my motion sensor lights?
Yes. Extreme temperatures can cause motion sensors to behave unpredictably. In cold weather, sensors may become less responsive or take longer to reset. If your motion light stays on or off during seasonal changes, weather might be the culprit.
How long should a motion sensor light stay on after activation?
Most models stay on for 30 seconds to 10 minutes after detecting motion. If your light remains on for much longer—or doesn’t turn off at all—it may be time to adjust the settings or try a motion sensor light reset.
Why does my motion light keep turning on for no reason?
Your sensor might be too sensitive. Movement from trees, passing cars, or even small animals can trigger the light. Adjusting the sensitivity or repositioning the sensor head can help reduce false activations.
