Arlo Pro 3 floodlights activate each other in an endless loop all night

[Blally]

I have two Arlo Pro 3 floodlights that seem to activate each other as one turns on and the other turns off.  One is at the doorway and the other is facing a driveway. They are at a right angle from each other. There is no motion detected and each light stays on under 5 seconds.  As one turns off the change causes the other to turn on, and they go back and forth like this all night. 

I have set activity zones to exclude overlap (which defeats some of the reason for having the cameras) and it hasn't helped. I have confirmed that both floodlights have the most recent firmware update.  

Thanks for any suggestions.

Try turning down the motion sensitivity in your modes and rules instead of using zones. Do this in reasonably small steps until you get what you need. I would try steps of 10 until it stops the auto-activating and then slowly raise it to find a decent max setting.
