I have taken my post lamp apart and put it back together four times.
Symptoms are on and off at irregular intervals.
I replaced the bulb so it is not a bad filament.
I have taken the unit completely apart and checked all the connections within the lamp holder and retighten each of the wire nuts and taped those connections.
I replaced the light sensor and the problem continues.
I look out and it is lit; then I look out later and it is out.
I wonder if the circuit breaker might be opening and closing
Anyone have any suggestions ?
