In 1894, two new sets of range lights, the Palmer Range and Wrights Range, were established to work in conjunction with the existing Leards Range Lights to guide mariners into Victoria Harbour, also known as Crapaud Harbour. The following set of instructions was published for mariners to help them use the three pairs of range lights.
To enter Crapaud (Victoria) Harbour from the Strait of Northumberland, vessels should bring the two old lights (which will be known hereafter as “Leards range,” and which are both fixed white) into alignment and kept them in one on a north course until the lights of Wright’s range are in alignment when they should follow this range N.W. ¼ N. until the red light on Palmer’s wharf is in alignment with the front light on Leard’s range. These two in one will lead in from the black buoy at the entrance to the dredged cut, to the wharfs, N. N. E., but strangers entering at night are advised to anchor in the road at this last described turning point near the black buoy, as they will be in good anchorage inside the shelter of Tryon shoals, while it is not safe to attempt the dredged cut at night.
A year after Prince Edward Island joined the Confederation of the Dominion of Canada in 1873, the General Superintendent of Lighthouses visited the island to assess the status of its lighthouses. At that time, the light at Victoria Harbour, then known as Crapaud, was just a lamp raised on a pole with guide rods that was being tended by Donald W. Palmer. This light was erected in 1869 by George Clark, who received £10 granted by the island's government the previous year. A new lantern and reflector were provided to the station in 1873, and range lights for the harbour were recommended in 1876.
S. J. B. Leard was the first keeper of the Leards Rear Range Light, which is not surprising as the beacon was displayed from a mast attached to his home. In 1895, the mast was relocated to the keeper’s garden as the strain on the mast during gales was damaging the keeper’s dwelling. At the time of the passing of Keeper Leard in 1901, the rear light was being shown from a dormer window in his home. The light was subsequently transferred to a tower erected 61 metres (200 feet) north of the house along the same range line, and the day beacon shown above the ridge of Keeper Leard’s home was taken down.
The rear range tower was a square, pyramidal, open skeleton structure surmounted by an enclosed square lantern room from which showed a fixed white light at an elevation of 29 metres (95 feet). The tower was 14 meters (46 feet) tall from its base to the top of the ventilator on the lantern and had its side facing the range light cover with slats to forma day beacon. The rear tower has since been enclosed. Both Leards Range Lighthouses now have a vertical red stripe painted on their seaward face, and the towers are separated by 851.8 metres (2,795 feet).
As noted above, the Leards Range Front Lighthouse also serves as the Palmer Range Rear Light. When established in 1894, the Palmer Range Front Light was situated on Palmer’s wharf in Victoria Harbour and consisted of fixed red light shown from a lantern attached to a post at an elevation of three metres (10 feet). In 2008, the Palmer Range Front Light was exhibited from a square, skeleton tower, standing 5.2 metres (17 feet) tall and its signature was a 0.5-second red flash every second. The front range light is 120.7 metres (396 feet) from the rear range tower, which displays a fixed red light.
The Palmer Range Lights were temporarily discontinued in May 2008 as the channel had silted up. The lights were reactivated the following spring but have since been discontinued.
Abner J. Howatt was appointed keeper of the Leards Front Range Light on July 22, 1893, and James Inman received an appointment to be keeper of Leards Rear Range Light on August 13, 1901. Both keepers were making $100 per year.
Emerson MacDonald retired as keeper of the range lights in 1960 at an annual salary of $615, and Albert Trowsdale was then appointed caretaker of the automated lights at $200 per year.
Since 1990, the Leards Range Front Lighthouse has been operated as the Victoria Seaport Museum during the summer. Visitors are allowed to climb a ladder to the lantern, where they can get a good view of Victoria Harbour and a unique feature of the tower - its two lights. The museum has information on the harbour's three sets of range lights and the keeper's who were responsible for them. Other displays cover the history of the village and several of its historical buildings.
Leards Range was discontinued by the Coast Guard in 2011, but the front light remains active as Victoria Harbour Lighthouse.
Leard's Front Range Light was recognized as a heritage place under the Prince Edward Island Heritage Places Protection Act on October 3, 2012. On September 25, 2013, the lighthouse was awarded a Provincial Designated Heritage Place plaque and certificate.
