The Lighthouse stands on a reef extending off Rozi Island shores and is about 6 km North from Rozi mata Temple which is a prominent 150 year old land mark situated on the mouths of Rangamati creek. Kalwan is approachable during high tides by a motor Launch.

A black stone mound was constructed at Kalwan site during 1865-67 along with the development of Bedi Port under the jurisdiction of then princely state of Nawanagar (Jamnagar). The mound was provided to guide the vessels during the day time. Its improvement and transformation into a lighted beacon was carried out in 1917 when a regular steamer service between Bombay and East Africa via Rozi was introduced by M/s Bombay Steam Navigation Co. this lighthouse is an important navigational aid assisting ships to anchor at Rozi anchorage.

An oil wick lamp inside 6th order optic was placed on the tower in 1917. The operation of the light was controlled from Rozi mata temple from where an attendant used to bring the spare lamp in a boat during the late day tide and place the same on the tower. The light functioned during fair seasons only. Further improvement to lighthouse was carried out in 1950. An optic with higher range replaced the 6th order optic in 1958. The tower was remodelled in 1966 and a DA gas light of AGA make inside the 300mm optic integrating the sun valve was installed the same year. The light now started functioning throughout the year. 

The Light underwent modernization during 1993 and Solar Power operated light with halogen lamp (JLWL) was commissioned into service on 21st November 1993. The tower was affected by the earth quake of 26th January 2001 but remained in position for some time till it fell down subsequently.
