I think you might have won the prize. There's a panel in the emergency gen room that has three small lights, and from time to time, one is lit differently from the other two, and the engineers start looking for shorts. In most cases, this happens following heavy rain or seas and it's nothing more than water in an outside light fixture somewhere. There has been an occasion or two in which it was more serious.
