[Independence Day] What "language" or symbols was the helicopter trying to communicate use?

Specifically the modified copter with big flashing lights that was destroyed.

a common notion for communication to aliens that we are intelligent is to use patterns of prime numbers, this gets across the point that we at least have a basic grasp of maths and aren't just dumb apes and it doesn't require a common language. 
I know that those lights were specifically prime numbers, but we didn't see that much of them.
