The front lighthouse is a tapered, wooden tower, 17.3 metres (56.8 feet) in height from base to vane and square in design. Around 1948, the height of the tower was increased by 2.4 metres (7.9 feet), which resulted in the lighthouse having a somewhat awkward appearance, as the slopes of the upper and lower portion are different.
The rear lighthouse is a tapered, wooden tower, 14 metres (45.9 feet) in height from base to vane and square in design, but due to the hill on which the tower is situated, the light has a focal plane of 46.3 metres (151.9 feet). The rear tower is situated 650 metres (2,133 feet) north of the front range light
The front lighthouse was moved back from the nearby bank in 1902 and again in 1936. In 1934, the front range tower had a red diamond on its otherwise white seaward face, but today both towers have a red seaward face with a black vertical stripe.
The range lights originally displayed fixed red lights until 1902, when they were changed to fixed-white lights. The Haszard Point Range Lights currently show a fixed-yellow light.
Edwin Stewart was appointed keeper of the range lights in 1910 at an annual salary of $320. Prior to this time, a separate keeper was assigned to each of the range lights. Keeper Stewart retired in 1958, at which time he was making $1,020 a year, and subsequently served as caretaker of the automated lights for just $75 a year.
The Town of Stratford petitioned for ownership of the lighthouse under the Parks Canada Heritage Lighthouse Program.
