Most motion detectors have a built-in override: Normally the switch is kept on all the time. If you turn the switch off and on within a second or so, the light will stay on, and this overrides motion detection. To go back to normal operation, turn the switch off and wait ~10 seconds, then turn back on. Click to see full answer. Moreover, why does my sensor light not turn off?Most motion sensor lights have a built-in “override” mode. What to do: Shut the lights off at the breaker and wait a full 30 seconds before turning the power back on. After this, the security light should come on for a short while then turn off again and go back to normal settings.Beside above, how do you reset a motion sensor light? Turn the light switch on and off rapidly approximately four times. The light will eventually stay on continuously. Once the light is on, turn the switch off, wait five seconds and turn it back on again. The light should stay off and the sensor should be reset. In this regard, how do you fix a motion sensor light stays on? How to Reset a Motion Light That Stays on All the Time Move the motion sensor to a position away from an exterior air conditioning unit, a dryer vent or a heat vent. Position the sensor away from objects such as trees and shrubs. Check the time switch to confirm it isn’t set in “Test” mode. Reset the light to make sure it isn’t set to manual operation. How do you trick a motion sensor?Move slowly along the walls in which the sensors are located, and as low as possible, while proceeding forward. Many motion sensors have blind spots that make it difficult to detect movement directly underneath them. Be aware that another sensor may be pointing in your direction from the other side of the room.
