Pentakota Lighthouse is situated about 13 Km from Tuni Railway Station on Visakhapatnam-Rajahmundry section.

A brick masonry pillar was constructed here during the early part of the 20th century wgich served as a day beacon.

The present Lighthouse was constructed during 1955-57 and a D.A. Gas equipment supplied by M/s B.B.T Paris was installed on the tower. The lighthouse was commissioned in June 1957. The D.A. Gas light was discontinued and 250W 230V incandescent lamp with electrical drive of optic assembly was installed in January 1991. Due to frequent mains failures a 100W 12V halogen lamp with electronic flasher was introduced inside the drum optic fitted over the main optic assembly to function as emergency source in December 1997. The system operates on electronic flasher with batteries charged by SPV module. The main source incandescent lamp was replaced 250W 230V Metal Halide lamp in April 2002.
