Click_Button_BatteryRechargerFlashlight.wav

One Friday night, me and my partner were eating dinner, and we both heard a click. She perks up, "what was that?" and I said "the dryer is running, probably something in it" and she goes "No it was inside" (our dryer is like a back door outside porch kinda deal). I noticed it came from inside as well, in the kitchen, but mentally shrugged it off because lasagna. But now I know she heard it inside too, so I walk in the kitchen where the sound came from and don't see anything moving or on. I took note of where my cats were in case anything was being chewed on: One in bed, one on the couch, they aren't chewing on anything or are even near the clicking sound, so back to dinner.
About 45 minutes later, dinner is wrapped up, my partner is asleep and I start turning off all the lights. When I turn the kitchen lights off, there is a light that stays on in the corner. I have a car battery recharger there: It has USB ports in case ya lose power, charger cables, and a flashlight attached on the side.... which is on. I turn it off: exact same click that I heard earlier.
Do I have a ghost?
