My light connected to a sensor switch(on/off motion detector and day night detector) stopped working about 6 weeks ago. The light never came on at night when there was motion in front of the sensor. Then 3 nights ago it came on when I drove in and since then it has worked normally.
What would cause it to stop working for 6 weeks then without any repair or adjustment, just start working again?
The switch is a standard unit sold at Home Pro and all around, the light is an LED tube unit.
