Strange light over remote fishing village in Southwest UK

This footage was recorded with a camera phone at 3 am December 29th, 2012 in a remote fishing village in southwest England.

Witness: "It was hard to record and keep the background into picture.

Behind the hill there is water and a pier and on the left some fishing building club. The actual object it was further then it seems as I had my phone in full zoom."

What is the cause of this phenomenon, a laser show, a hologram, a UFO or is it more mysterious?
