The Gjerdholmen lighthouse is a cylindrical, white fiberglass tower standing 6 meters tall with a focal height of 8 meters. Located on a small island off the southeast coast of Kvitsøy in Norway's Rogaland region, it guides vessels through complex channels and around numerous rocky islets.

This modern structure replaced a previous square wooden tower after 1999. The lighthouse offers a geographic range of 9.7 nautical miles.

Why it matters: This lighthouse is essential for safe navigation around the Kvitsøy archipelago, especially for vessels navigating the southeast coast. Its sector light offers precise directional guidance, assisting mariners in avoiding hazards within the local channels.
