sentences:  Landing lights are used during the descent and approach to landing, and at other times if deemed necessary by the flight crew or operator.These lights can generally be found attached to any tall structure such as broadcast masts and towers, water tanks located on high elevation, electricity pylons, chimneys, tall buildings, cranes and wind turbines.Shorter structures that are located close to airports may also require lighting; an example of such is the south scoreboard at Lambeau Field in Green Bay, Wisconsin built in 2013, which is the tallest structure in the general area of nearby Austin Straubel International Airport.
