How to Make a Motion Sensor Light Stay On? - Rayzeek (2024)

Motion sensor lights are great at saving energy and bringing convenience to our life. They can automatically turn on the light for us when detecting motion from people or moving objects in the area and turn off the light after they leave and the detecting zone is vacant to save energy and reduce electricity waste.

Motion sensor lights can be used indoors for illumination, decoration, and light automation or used outdoors as a security light to detect intruders and keep your family members safe.

Motion-activated lights can have many forms. It can be a standalone motion sensor light with an integrated built-in motion sensor, such as a security floodlight that is ready to use out of the box. Or you can install a motion sensor light switch or wire a motion detector to your existing light to make it function as a motion sensor light.

A motion sensor light works automatically, but what if you want to keep the motion sensor light on?

Why Do We Want the Light to Stay On

Motion sensor lights are designed to automatically turn off the light if no motion is detected after a pre-set timer expires. For example, if you set a 20-minute timer, after the space is empty with no people, your light will keep on for another 20 minutes before turning off, to keep providing consistent illumination.

Though with an adjustable time delay range from 30 seconds to 30 minutes, the motion sensor light is applicable for most usage scenarios. There are still some situations where we need the light to always stay on for a better experience.

For example, motion sensor lights are ideal for outdoor usage, such as illuminating your backyard or garden. Still, sometimes we might want to keep the light on all night regardless of whether there is motion detected or not in the yard. For instance, when you are having a party with friends in your garden at night, you need to leave the light on for as long as it needs. If the motion detector is originally positioned to detect the people from the pathway, not the current partying area, the sensor might have a problem detecting motion, resulting in the light constantly turning off. And that can be a huge headache during party time.

It’s the same for indoor motion sensor lights. Sometimes we want the light in the stairway or study to stay on for a long time regardless of motion detection. For example, when we are having a good read in the study and the motion sensor is located far from us and unable to detect small and fine motions like turning pages, the light might frequently turn ON and OFF, which ruins the mood.

How to Make a Motion Sensor Light Stay On

Now we know that there is indeed quite a lot of need for a motion sensor light to stay on. And it’s inconvenient that we have to give up the advantage of a regular light that can stay on permanently by simply leaving the switch on, after we have “upgraded” all our lights to more advanced motion-activated lights. So how do we keep a motion sensor light stay on?

To keep a motion sensor light on, you can add a bypass switch to independently power the light, quickly switching the motion sensor ON&OFF to get the sensor stuck at ON position, or use a motion sensor light switch with an ON/OFF feature to keep indoor lights ON.

Quickly Switching the Motion Sensor On and Off

One of the quick tricks you can try is to quickly turn the motion sensor ON, OFF, ON to override the motion detection and make the light stay on.

To go back to motion detection mode, turn the motion sensor off, wait for about 10 seconds, and then turn it on again. The motion sensor will go back to the standard motion detection mode.

Why Does This Work

Some old PIR motion sensors are sensitive to voltage spikes or power surges, so the PIR motion sensor might get jammed and stuck at either ON or OFF position after a power spike caused by turning ON and OFF quickly.

This is also why you might see some motion sensor lights may suddenly turn on right after you turn on an air conditioner or washing machine inside the house. The heavy load appliance causes a voltage spike that triggers the motion sensor light to turn on.

There are people who claim that some old motion sensor lights have this “feature” built-in, but we don’t know for sure. Additionally, some new and advanced PIR motion sensors are resistant to power spikes so this trick won’t work. But this is definitely a trick worth trying because it does not require any tools or DIY installation.

Hardwire a Switch to Bypass the Sensor

You can hardwire an additional light switch parallel to the motion sensor, so you can power the light independently, bypassing the motion sensor. This way, the light can be powered by both hot wires from the motion sensor and the light switch.

If you need to keep the light ON, you can simply turn on the switch. Now the light is powered straight from the hotwire from the switch’s line. Whether the motion sensor detects motion or not, it does not matter. The light will keep ON as long as you leave the switch ON.

If you want the light to switch back to motion-detecting mode, you can turn off the switch. Now the light only gets power from the motion detector. Whenever the motion sensor detects a valid motion signal, it will supply power to the light to turn on the light and cut off the power when the space is empty with no people.

The hardwire bypass method does require some wiring and manual work, but it’s a guaranteed method. And it can be fairly easy or a little bit complicated depending on the type of sensor light you have:

A Light Connected to a Motion Detector

If your motion sensor light is a combination of a motion detector and a standard light, it can be fairly easy to add a switch because the wirings are clear.

Select a switch from your house that is not in line between the sensor and light, and connect theoutputhotwire of the switch to theinputof your light(which is also connected to the motion sensor’s output). It’s as simple as it is. Now the motion sensor and manual switch are parallel, and both can power the light.

You can have your imagination here to use a 3-way or even a dual switch for more precise control. For example, for the previous setup, it’s not possible to keep the light off because the light might still get power from the motion sensor. You can choose to keep the light off by adding a main switch to the motion sensor. It’s simple as well by wiring the main switch’s output to both inputs of the switch and motion sensor. In this way, you can turn off the main switch to keep the light off for as long as you like.

A Motion Sensor Light With Built-in Sensor

Now, this can be tricky because the motion sensor is built-in, and you only get three wires from the motion sensor light. Though the theory and wiring are exactly the same as above, you have to disassemble the motion sensor light and do a lot of rewiring.

Some lights might be easy to rewire, and some might not. If your light is not easy to rewire, it’s recommended to upgrade it with a new one with an ON/OFF feature built-in, which is designed by default for users to control the light with a switch manually.

Note that this solution is for both outdoor and indoor motion sensor lights but mainly for controlling outdoor lights. For indoor motion sensor lights, we can have better options, such as using a motion sensor switch with ON/OFF feature. And many of the indoor lights already have built-in manual control settings because home users frequently need to adjust them, such as motion sensor strip lights and night lights, unlike the outdoor lights that are rarely adjusted once properly installed.

Use a Motion Sensor Switch With On/Off Feature

If your indoor motion-activated light setup is a light fixture controlled by an occupancy or vacancy wall switch, the best way I’d recommend is to use a motion sensor switch with an ON/OFF mode directly. With the ON mode enabled, you can keep the light ON permanently and keep the light OFF with the OFF mode selected, the same as a standard ligth switch.

These types of motion sensor switches have a built-in manual mode to make the motion sensor work like a normal light switch, regardless of any motion detection. And you can switch back to normal motion detection mode fairly easily by pressing some buttons on the switch panel.

For example, our Rayzeek RZ-021 motion sensor light switch allows users to quickly shift the motion sensor switch to a standard light switch by pressing the small button. It’s extremely fast and convenient to select from ON, OFF or back to the previous motion detection mode with one button.

Why it’s best to use a motion sensor switch with manual mode?

First, by utilizing a motion sensor switch with a manual ON/OFF function, you don’t have to add another light switch to control the light. It just seems redundant and a waste.

Second, motion wall switches are particularly cost-effective nowadays. Compared to adding a manual switch, the cost of replacement with a new motion sensor with manual mode is pretty much similar.

Lastly, a standard occupancy or vacancy motion sensor switch is not always better than a regular light switch. Even though a motion sensor switch is more advanced, automated, and energy-efficient, we will still think of the good old toggle light switch when we need to keep the light ON for the whole night, which is not achievable with a normal motion sensor switch. But you can definitely enjoy the best of both worlds with an ON/OFF motion sensor light switch from now on.

Conclusion

Sometimes we do need to keep the lights on for special purposes. In most cases, motion sensor lights are better than standard lights. Finding a balance between motion activation and manual control is always an ongoing and interesting topic.

We hope this guide can help you find the best way that suits you to keep your motion sensor light ON and better enjoy your lighting in everyday life.
