If it is not faulty, you should probably reset its sensitivity level. Motion sensor lights ensure the safety of the property and everyone within it.
So it is necessary to fix them as soon as they start malfunctioning. Here is a long article guide to help you understand and solve various motion sensor light issues.
Read it thoroughly and try to fix your equipment. Alternatively, seek professional help for issues you cannot solve by yourself.
Motion Sensor Light Turns On and Off Repeatedly: 7 Common Reasons
If your motion sensor activates itself needlessly, try to understand the root cause. Observe the motion light closely to see its exact behavior.
Issues with your motion sensor lights will always be due to a faulty component or wrong sensor settings.
Below are the main reasons why your motion sensor light is constantly flashing.
01. You have a damaged bulb
Are your indoor or outdoor motion sensor lights flickering nonstop? If yes, the bulb could be faulty.
Even if your fixtures are new, the bulb or the diode could malfunction. Bulbs are the first suspect when motion sensor lights repeatedly turn on and off.
02. A connection fault
A motion sensor light will work only if the connections between various components are error-free.
If there is a disconnection between the diode or bulb and the light fixture, your light will continuously flicker.
If the connection between these parts is okay, there might be debris triggering a disconnection. Cobwebs or some dead insect bodies could also affect the sensor light.
03. Damaged circuit system
If you have a faulty electrical circuit, your motion sensor light will flicker aimlessly.
Again your sensors may be okay, but the light components are not.
A problem with the circuit system needs instant repair to keep the whole security fixture working perfectly.
In addition, the circuit can function well but succumb to a power surge problem.
Thorough troubleshooting can help rule out power source issues or motion sensor light’s circuit system.
04. Wrong positioning of the sensor
Does your motion sensor light point in the correct direction?
The incorrect positioning of the sensor can cause it to detect even the harmless things in the yard.
When the sensor light faces the wrong direction, it can trigger light due to moving tree branches or speeding cars outside the property.
05. Maximum range setting
A motion sensor light that is constantly flashing could be working at the maximum range setting.
Thus, it is turning on often because of detecting movements of things beyond your property.
Motion sensor lights should reveal intruders that have jumped onto the property. Those outside it do not matter.
06. Pet immunity mode is off
Even if you do not have cats and dogs, your neighbors do. A wrong sensor light setting can cause it to sense movements from pets.
There can also be tiny pests that cross your yard at night.
Deactivating the pet immunity mode can make you think you have a big intruder in the yard, yet it is only a pet or a tiny nocturnal animal.
07. Incorrect angle range
All motion sensor lights can operate at any angle range between 180 degrees and 360 degrees.
If yours has a wider angle range than it should, it will detect harmless movements in your compound.
As a consequence, you can wake up thinking you have an intruder only to find swaying tree branches.
So far, you have probably noticed one thing. When your motion sensor lights turn on or off continuously, it might have two causes.
First, the system’s bulb, diode, or circuitry may have a defect. And if that is the case, the motion sensor lights will flicker continuously.
If there are no issues with these parts, the motion sensor light’s settings are not okay.
Whether it’s the positioning of the sensor, a wrong angle, or range, these things can change the functioning of the motion sensor light.
Before you fix anything, check if there is flickering or not. If the lights keep on flickering, the odds are that your sensors are working.
When the lights turn on or off aimlessly, you have a problem with the sensor settings.
First, understand the source of the problem to solve it correctly and fast. We will tell you how to correct the aforementioned problems below.
Motion Sensor Lights
Motion sensor lights automatically illuminate when they detect movements in their range of operation.
Some fixtures are great for indoor use and others work better outdoors. Motion sensor lights use occupancy sensors to sense heat and trigger the light.
A few types of motion sensor lights exist. These include passive infrared, photoelectric, area reflective, microwave, and dual technology.
After sensing motion, the light can stay on until the intruder gets out of the range. A user can also set how long the light should stay on.
When buying the correct motion sensor lighting, consider its features. First, check the type of bulbs it uses, the leading one being the light-emitting-diode or LED.
In LED fixtures, diodes produce light as electricity travels through them.
Other kinds are incandescent and fluorescent bulbs. Each type of bulb has its pros and cons, so choose wisely.
Other features to consider are the sensor’s range and angle. Each product will offer these two features and the differences are in the settings.
The last feature to consider is an energy source. Mostly, you can find motion sensor lights that use battery power, solar energy, or electricity.
Pick the best motion sensor lights for maximum security and peace of mind.
Solutions For The Problems
01. Change faulty bulbs – Solving a problem with a faulty bulb is easy. Just get a new one. Find the exact bulb for replacement. So, check if you have LED, incandescent, or fluorescent bulbs.
02. Fix the bad connection– If you are good at do-it-yourself tasks, open the motion sensor light and inspect it. Whatever you find between the diode and the lighting fixture is the problem. Solve the issue accordingly.
03. Repair the faulty circuitry–Unless you can solve issues in electronic gadgets, do not do it. Instead, hire a professional to check the circuit system of your motion sensor light.
04. Reposition the sensor– Checking the motion sensor light’s direction is easy. If you notice that it is pointing in the wrong direction, reposition the sensor. After that, it will capture only the field that matters.
05. Lower the maximum range –If your motion sensor’s sensitivity range is in the maximum setting, adjust it slightly. Bring it back to a lower sensitivity level to let the sensor detect relevant movements.
06. Enable the pet immunity mode – Modern motion sensor lights have a pet immunity mode. If small animals are within their range, they will not turn on. For that to happen, you must enable the pet immunity mode on the device.
07. Alter the angle range–Check if your motion sensor light is running beyond the best angle range. Then, make the angle narrower by covering both sides of the device with electrical tape.
