One of the biggest and most important parts of a security system is the motion detector lights. These are designed to come on and light up when detecting that someone or something is moving around in the area. But it’s important that they’re adjusted the right way. If they aren’t sensitive enough they may not come on when needed — and if they’re too sensitive they could come on too frequently. For example, a homeowner doesn’t really want to have their motion detector light come on every time a rabbit hops through their yard or a bird flies by their window.

But they definitely want it to come on when someone walks up on the porch — or if there’s a bear trying to get into their trash cans — and that means giving the detector enough sensitivity to catch those things. Eventually a motion detector light may need to be reset, too. There can be a number of reasons for that to happen, and when or if it does the goal is to get it working quickly again so it can continue to help the homeowner be protected. Fortunately, it’s generally not hard to reset motion sensor lights, and most homeowners can reset their lights easily in just a few minutes.

    Motion Detector Light Bulb: Why Won’t The Light Turn Off?

    The opposite problem of your motion detector lights not turning on is when they won’t turn off. This never-ending glow can happen for many reasons. However, you’ll want to quickly troubleshoot and fix whatever the reason may be so your light bulbs don’t burn out. Also, the sooner your motion detector light bulbs work is the sooner they’ll get back to keeping your family safe.

    Don’t Let Your Lights Be So Sensitive

    Typically, motion detector light bulbs have their own unique sensitivity that you can adjust depending on their range setting. If your motion detector light bulb’s sensitivity setting is too high, then even the smallest movement will turn the light on. This means movement like a butterfly flying away or a leaf falling to the ground can create light. Lower the sensitivity to track the bigger, and often more important, movement. Another tip is to avoid placing your motion detector close to a busy street as this will most likely pick up unwanted activity.

    Speak to a security expert to better understand and adjust your light to the appropriate settings for your needs.

    Check Your Settings

    Similar to sensitivity settings, you can control how long your motion detector light bulb glows. Some motion detectors let their light glow for up to 30 minutes. This will surely give you the impression that your lights never turn off. You can prevent your motion detector light bulb from glowing too long by adjusting your device’s duration settings. Many sources suggest leaving your duration setting at one to two minutes at most.

    If after troubleshooting you find that your motion detector light bulb is still not turning off, seek consultation from a security expert.

    Motion Detector Lights Sometimes Need Resetting

    After a power surge or other event that affects the electrical in a home, a motion detector light may need to be reset. This can be very important, since a homeowner who doesn’t reset their light may be unprotected. But it’s not difficult to reset a light. You should check your detector’s light periodically to make sure they’re reset the right way and working correctly.

    In some cases a homeowner who doesn’t go into that area very often after dark may not understand that a motion sensor light isn’t working. They may not realize it at all, and once they see that it’s a problem they can quickly take care of it.

    Checking the light frequently and troubleshooting the light if there’s an issue with it are the best ways for a homeowner to have good working protection in their security system. It’s also a good way to make certain that they have more peace of mind, as well.

    Why Would a Motion Detector Light Need Reset?

    With any security system there can be occasional glitches. These can include needing to reset a motion detector light, and there are several reasons the light may need to be reset. These can include:

    • faulty sensors
    • bad bulbs
    • electrical surges
    • power outages

    There may be other reasons, as well, and it’s valuable for a homeowner to take a careful look at what’s causing the issue. Having the right troubleshooting can matter, as can replacing any motion detector lights that can’t be reset or repaired successfully.

    Troubleshooting Doesn’t Have to be Difficult

    The best way to reset a motion sensor light is to turn it off and back on again for a period of 30 seconds or longer. A homeowner can also turn the power to it off at the breaker, in order to ensure it has time to reset itself. If that doesn’t work the sensor or the bulb may be to blame. Replacing the bulb is easy — and replacing a sensor isn’t something that’s normally done. Covering the sensor to test the light is an option, but if the homeowner doesn’t have success with that they may choose to replace the light so they can have proper security and peace of mind again.
