​The 1833 General Lighting and Beaconing Plan for the Mainland already provided for a port light for Cabo Raso.

The Commission of Lighthouses and Beacons met on January 16, 1884, decided to establish a 4th order lighthouse with white flashes every 1 minute, indicated in the general plan, and that the light from the Cabo Raso lighthouse be placed in the fort de S. Brás, in a masonry tower 15 meters high. This project was approved by the Commission on April 30, 1885. However, this was not the adopted solution, opting for a less expensive one.

«In front of the window and on a slab of stonework, there will be a light fixture, which has just ceased to be used in Olhão and which has a luminous range of no less than 5 miles which, in the indicated position, will illuminate a sector of 240º between the 20º HUH. and 40º by 0, being the red light. During the day, the equipment will be collected inside the house by means of a mobile cart on rails, resting on the slab, being placed on a wooden platform or fixed table.»
David Xavier Cohen, Descriptive and Justification Memoir, 15 May 1893.

The lighthouse thus constituted came into operation on January 1, 1894, equipped with a dioptric device, an oil lamp producing a fixed red light.

In 1915, a metal tower 13 meters high and 23 meters high was erected, and a 5th order optical device was installed, with a fixed red light.

The optical device was replaced by another one with 6th order rotation (150mm focal length) in 1922. It began to emit, instead of the fixed red light, groups of two red flashes every 10 seconds. The light source consists of an oil lamp and the rotation of the optics is produced by a clockwork mechanism.

A building for the installation of the sound signal was designed and built in 1925.

In 1927 the audible signal was replaced by a siren powered by compressed air, powered by one of two petrol engines.

The lighthouse was electrified by means of generating sets in 1947, and the light source became a 3000W lamp.

It was connected to the public distribution power grid in 1969.

In 1984 it was automated. The 6th order optics were replaced with a rotating pedestal of sealed optics ("PRB"). A new sound signal (CEFA 1000) was installed.

In the year 2000 a new telesignage system was installed.

In December 2003, the PRB-46 was removed and an ML-300 flashlight fitted with a TF 3B eclipsor and 50W12V bulbs.

It was connected on January 19, 2009 to the public water supply network, as part of the counterparts of the protocol for the creation of the lighthouse museum of Santa Marta.
