Saucer shaped object, flying slowly and silently, with coloured lights moved towards the bright light. I signalled to it,

I was standing outside my back door seeing my friend off - she was going to walk home. I lived in a remote area, near some woods and church. It was about 9pm. 
As we were standing there, I saw what looked like the'Star of Bethlehem' type of bright light hovering over the area where the church would be, although the Church itself was obscured by trees. 
I signalled to it by switching the outside light on and off - We continued to watch when we saw a craft which was flying low and silently across the tops of some trees it had bright lights (I thought they were coloured - ) and it moved across and then seemed to join up with the bright light, it merged with the light, glowed, pulsed, and then shot off up and across the sky it just disappeared really quickly.
I was working at the time about 21 years old, the person with me was female about the same age and worked in the Crown Court for the district Judges.
Later I found out that a lady who lived in a big manor house near attached to the Church had seen something hovering near to her windows and had called the RAF. She was a Justice of the Peace.
Witness indicates that the date of the incident is approximate.  PD
