The lighthouse was named after Major-General Sir George Charles d'Aguilar and began service 6 April 1875. The light was a fixed dioptric first order Fresnel lens, emitting a white light on a focal plane of above sea level, that could be seen in clear weather . When the Waglan Island Lighthouse began operation in 1896 the Cape D'Aguilar light was rendered obsolete. In 1905 the light was removed and transferred to the Green Island Lighthouse to replace the forth order Fresnel light. In 1975 the Cape D'Aguilar was placed back into service with an automated system. The existing structure is tall.
