Lower Light is a township adjacent to Port Wakefield Road in South Australia's lower Mid North.[4] The township of Port Prime was surveyed on the coast of Gulf St Vincent in 1880, but little remains of that town now, and it is included as part of the bounded locality of Lower Light.[5]
Lower Light is named for the lower Light River estuary into Gulf St Vincent directly south of the settlement.
Lower Light has also been the location of parachuting/skydiving operations since 1962,[6] which operate from the George Quigley Airfield, located a short distance north of the township.
