The light was supposed to be erected on a tower of 23 feet (7.0 m) from ground level to focal plane of light, showing a white sector between red over the required angle. The construction suggested was a circular cast-iron tower, in which the weights controlling the clock would work. The tender amounted to £1852 for the light and £525 for the tower f.o.b. London.[5]
The site for Batu Tinagat Lighthouse was chosen from the recommendations of Captain Frederick Charles Learmonth from HMS Merlin, a Survey Vessel, doing naval cartography for the British Admiralty.[6] Captain Learmonth acted also as technical advisor for the lighthouse.
Following World War II, the lighthouse wall was damaged by the effects of aircraft machine gun attacks by either the JapaneseorAllied forces.[2] After the end of the war, the British colonial government approved a total of $80,595 to repair the lighthouse. By 1999, its source of light was delivered using solar energy until it was replaced by a new lighthouse in 2008.[2]
On 23 February 2018, it is one of 24 heritage sites in the state that were gazetted by Sabah's State Heritage Council under new enactment of "State Heritage Enactment 2017".[7][8]
