Electrical Wiring in the Home/trouble with outdoor light staying on


i have a outdoor light with a day night sensor.when it becomes dark the light comes on but through the night it goes on and off,could you please give me some idea as to why this happens.


Most likely the sensor is too close to the light.  It sees the light, thinks it is daylight and shuts off.  Then it is dark, and it turns on.  It keeps doing this.  Try to point the sensor away from the light.  If this does not help, the sensor may just be bad.  They are temperamental.
