I have quick question. One of our security lights started flickering on and off on the day we had that heavy rain. We switched it off and then back on the next day but now it doesn't work. As soon as u switch light ON, bulb comes on and then goes off after like 2 seconds. But then that's it. It does not come on when it detects movement. It doesn't make that clicking noise like the other light. Do u think the sensor has gone faulty?
