Opener Lights Come on uncommanded

I have this strange issue I have been unable to solve. I have 2 separate garage doors that each have a Craftsman 1/2 up opener. I have wall remotes that have a motion sensor that activate the lights on the openers when they detect motion. Lately, I have been finding the lights on in the garage when no one has been out there for hours. I even put a remote camera out there to see if something was tripping the sensors. The wall remotes are side by side but the openers and remotes are completely independent of one another but I always find the lights on both openers...never just one. The only device that is linked to both openers is my wireless remote on the outside of the garage and I installed a new one as a possible cause. I have had this setup for nearly 10 years but the issue is less than 6 months old. Has anyone else seen this or have any ideas? Thank you in advance for any help!
