Saw two, red circular lights

So last night around 10:30ish pm, my husband and I heard a sound of an object that hit the ground in our enclosed laundry room that has French doors that lead to our back yard. We think nothing of it and don’t react until 3 minutes later when we hear it again. My husband goes to check and finds nothing out of place. Weird but not worrisome.
Then about 11:10 pm I go to the kitchen to put something in the sink and when I look out my kitchen window, I see two red lights moving simultaneously to the left toward our tenants cottage. It startled me and I jumped back and looked again and it continued to move in the same direction. They appeared to be the size and circumference of a lid to a pickle jar. It was about 20 feet away from the window. We have four outdoor sensors but none of them went off.
I asked our tenants if they were out with a flash light or thought it might be a lights from an emergency vehicle but it was two steady, circular lights. Not flashing, not blinking, not a stream. They were two lights in tact.
