Also know as hat lights. The goal of a path light is to act primarily as down lighting, essentially lighting up areas from knee level down. They offer more beauty to your landscape as well as increased visibility on your walking areas allowing you to have a surer foothold when getting from point a to point b. They are primarily used around pathways and in flower beds.
Pathways
Along pathways they can light up sidewalks, pavers, patios, and the edges of a driveway.
Flower Beds
They can also be used amidst small flower beds with shrubbery emitting a nice effect among shorter bushes and plants.
