I have the traditional two light at the left and at the right of my garage door. The are on the same circuit with the porch light that has a PIR sensor (turns on when move is detected).

So it is power source-->switch--Porch light--first light--second light

In the evening when we turn these lights on from inside the first light is flashing like those on the police cars :-), it keeps doing that for a while (can't say how long, it is not a regular interval) and then it stops flashing and it is solid on. Sometimes the same light turn off and stays like that

What could be the reason for this?

    Does this answer your question? What could cause flashing LED lights when other LED lights in a different room are turned on? If not, many such questions have been posted. Short answer, try different bulbs or devices. – isherwood Feb 16 at 15:45
  • Yes it points me to a possible smoking gun. I do have a chandelier which might be on the same circuit that has 9 of those spiral bulbs ..these are on a different switch but yes different bulbs (the outside ones are LED) . What does not make sense is why the other LED bulb is not flashing – MiniMe Feb 16 at 15:49
  • It's the nature of the beast. I have two identical motion/light-sensing fixtures with two identical LEDs on the front of my garage. One blinks all day if the switch is on. One doesn't. – isherwood Feb 16 at 16:01
  • Are there any smart switches, lighted switches, dimmers, anything like that in line? Is the PIR wired so the garage door lights come on when the PIR senses motion? – Harper - Reinstate Monica Feb 16 at 16:49
  • no sensors, old school lighting. The only new era thing there is the PIR sensor No the PIR sensor turns on the porch light only. The garage lights used to have a senor but it is gone on both.. they are in parallel with the porch light bulb – MiniMe Feb 16 at 16:53
