Bliss Island Lighthouse

Bliss Island lighthouse was first constructed in 1871 and was lit on 1st December of that year. The lighthouse was initially a square wooden tower, painted white and exhibited a fixed red light produced by five flat-wick lamps backed by reflectors.
In January 1901 the character of the light was changed from fixed red to fixed white which increased it's range considerably.
In 1903 an iron lantern replaced the original wooden one and the height of the tower was increased to 40 feet. At some point the wooden tower was replaced with a concrete one so it is likely this was at this point though I have been unable to find confirmation of the date. Also in 1903 a new fifth order lens was installed from Chance Brothers of Smethwick near Birmingham, this emitted an occulting white light with a characteristic of 10 seconds of light followed by a five second eclipse.
This lighthouse was replaced by a new structure in 1964 that now once more emits a red light. The old one still stands next to the new one though I have been unable to find out if the original lens is still in situ.
