Nine Orange lights appeared and headed out to sea.My wife and I were walking along the beach when we saw an orange light appear from behind a Hill to the North of us. The light was circular and moving quite quickly. It was not an aircraft as it had no navigation lights, beacon or strobe light. After about 30 seconds another similar light appeared. This continued and we counted nine lights that appeared from beyond the hill at regular intervals and headed out to sea in a North Westerly direction. It was difficult to estimate the size of the light as its distance from us was unclear. The lights stayed the same orange colour while we watched them. Eventually we could see all nine outlined against the stars as they began to get fainter and eventually disappeared from sight. There was no sound associated with the lights.
