I have a pair of LED porch lights. One of them has started to flash/flicker. Do I need to replace it? It is not a bulb; it is built in. It is extremely cold out. Could that be a factor?
I had this happen and it turned out that there was an outdoor circuit with 12 outdoor coach lamps on it. Flashing meant "find the bad bulb". I wound up replacing all of the bulbs a few flashing sessions later as it often counted old bulbs with poor seating as bad. I prefer a non flashing system tbh.
