Photo by myself in Midtown.
Some of the street signs in Midtown are internally lit with LED lighting. As a result, street lights aren't needed and people can find their way in the dark.
The stretch of Fifth Avenue between 42nd Street and 23rd Street is relatively quiet at night. Most of the businesses there are open only during the day. Lighting the way for pedestrians at night therefore is an issue.
