three vertical red lights in the sky

I was sitting down on a chair breastfeedingmy 10 month old baby, I saw three red lights on the sky above the tree line. I had lived in that house for 10 years and there were never any lights such as these there.  They were the size of car lights, but in the sky.and in vertical row.  I got up to see better and they dissapeared.  I sat agiain, then they appeareed again. I felt that they were watching me, so I close the curtains.  Next day, my friend told me that someone in the area had seen the red light also.
