The Charlevoix South Pier Light Station is located on Lake Michigan at the entrance to Lake Charlevoix in Charlevoix County in the U.S. state of Michigan at the end of the south pier/breakwater of the channel leading to Round Lake in the city of Charlevoix.
The first light in Charlevoix was located on the north pier. It was built in 1884 in order to guide ships to the newly improved Pine River channel. A lifesaving station was built just north of the lighthouse in 1898 and an oil shed was built in 1890. The first tower was 56 feet (17 m) tall, with a 61 feet (19 m) focal height.
The original structure survived for 63 years, but due to terminal deterioration the decision was made to replace it in 1947. In 1948 the new steel structure was installed and the light was moved to its current location on the south pier where the lens and lantern from the old structure were transferred to the new one. The skeletal structure and general configuration of this light shares some design elements with the Alpena Light. The South Pierhead light was originally painted Daymark red.
In 1965, because the Pine River channel is near a congested area, the Coast Guard vacated the old U.S. Life-Saving Service Station (tearing down the shingled building), and relocated to the grounds of the old Lighthouse Supply Station.
In 1989, the present steel and concrete pier replaced the old wooden pier with its concrete covering. The present piers and revetments were constructed in the 1970s and 1980s. The construction is specially designed to withstand unusually forceful wave pressures, and to protect the harbor. As Terry Pepper wrote:
The skeletal north pierhead tower has since been removed.
The 12-inch (300 mm) Tideland Signal ML-300 acrylic lens is described as a medium-range modern Great Lakes lens with a maximum range of 10 nautical miles (19 km; 12 mi).
The North Pierhead Light is at coordinates 45 19 18 N 85 15 54 W, and its characteristic is Flashing Green 2.5 seconds. The current tower is 20 feet (6.1 m) and it is an active aid to navigation. The former North tower's height is 56 feet, with a focal plane of 61 feet.
