Series of amber (orange) lights over North Myrtle Beach S,C

We seen several amber (orange) balls of light. At times there would be 1 light that lasted a few seconds and sometimes there would be 2 or 3 lights that did the same. They were over the ocean and stayed in the same spot. They would be there and then dissappear. This happened at least 4 times all in about 30 to 40 minutes. The lights would sometimes look like a line and sometimes not.They sometimes looked as if it were some kind of round object as well.
