I can't answer the cause of usage trends, sorry. However, the phrase on and above is grammatically acceptable, particularly in the quote.

Edit: Having now read the context, "on and above" refers to lights on the Empire State Building but also street signs. It might also be metaphorical for people's choices from the "man on the street" to the heights of power such as those in Office. Regardless of interpretation, "on and above" is appropriate.
