 The lighthouse was brought into operation at noon on 6 September 1971, whereupon the lightship was towed away.Initially, the light source was a 1,000 watt bulb set within a revolving 3.5 order catadioptric optic, mounted in a superstructure on the corner of the platform.Beneath the lantern, on two intermediate levels, were the sounder, air tanks and associated equipment for the diaphone fog horn, below which the main control room was located (on platform-level).
