Wired Ring floodlight Cam issues

Hi. Having issues with Floodlight Cam. Have had it for several years. (I believe it is a Gen 2) 1> new issue: lights are suddenly very dim. At 7:00pm, pizza delivery, motion detected, lights bright as always. At 8:30pm my son came home (and ever since) when they detect motion, there is a flash then the lights are on, but very dim and flickering. Nothing changed during this time… no storms, no power surges, no wifi interruptions. Any help why this sudden change? Time to replace or is there a fix? **UPDATE ** Today my was out shoveling snow. Black sweatpants, dark olive green jacket, black ski hat. Live view camera shows his entire outfit in shades of red. Does this mean the camera as well as lights are no longer working? I should replace whole unit?? 2> has been happening for over a year… Motion detection settings… set to Minimum Person detection on. Motion zones set up to only closest part of driveway. Our neighborhood is very dark, no street lights. Everytime a car passes by, headlights reflect off blacktop in driveway set off motion lights. So light is constantly going on and off. Plus, only some of these times when motion is detected result in video recorded. As annoying as the constant on/off of the lights, I don’t understand why it only records some of these. (On a wet rainy night, I have to snooze alerts to my phone because it goes off every time a car drives by and reflects off the wet blacktop)
