Tapping and large red light in my yard. Then it disappeared. Did not see a ship

Woke up to tapping on the glass sliding doors in the bedroom. Sounding like a insect flying into the glass. I sat up to see what it was and couldn’t see anything. My husband heard the noise and asked what is was. At that time I looked out into the yard seeing a large red light in the trees on top of the hill. As soon as I asked my husband to look at the light. It disappeared and the tapping stopped. Was very unsettling!
