About Sepat Lighthouse

Sepat Lighthouse is a cylindrical tower standing 14 meters high, situated on a shoal approximately 16 kilometers southwest of Tanjung Gebang. It emits a white flash every 4 seconds, visible for 11.6 nautical miles. The structure, a round tower supported by piles, is located near Sepang, Selangor. This active aid to navigation guides vessels through the Strait of Malacca, warning them of submerged dangers. While the site is accessible by boat, the tower itself is closed to the public.

Why it matters: This lighthouse is important for ships navigating the Strait of Malacca, warning them away from shoals along the southern edge of the shipping lanes and helping to prevent groundings.
