About Bontang Fifth Range Rear Lighthouse

Also known as: Bontang Fifth Range Rear (0G)

The Bontang Fifth Range Rear light stands 16 meters tall on a square platform supported by piles. This square metal tower is painted white and houses the light at the same elevation. Its white light features an isophase characteristic, meaning it is illuminated for three seconds and then dark for three seconds, completing a cycle every six seconds. Located within Bontang harbor, it is positioned 300 meters southwest of its companion front light. The operational status confirms its ongoing role in maritime guidance. The nearest port, Bontang, is 2.6 kilometers away.

Why it matters: This light, along with its front counterpart, forms a range that precisely marks a safe channel within Bontang harbor, essential for vessels navigating the port's shipping lanes.
