Morse code

[Poro Andaluz]

We haven't finished Barbara's map yet and I can tell you it's the worst Morse code puzzle I've ever done. I had to look up the solution in a guide because I could only see meaningless light patterns going fast. If some developer or someone could explain it would be nice.

Look at each individual square's light instead of looking at all 4 of them at the same time (I did that and realized it's impossible).

It's a 4-digit code and 4 squares, each representing a digit in Morse code. Hope this makes sense.
