The lighthouse is a navigational mark. It emits WHITE light. That might not be important to anyone who has not been to sea or lives inland but it is a very important point. Orfordness is a sector light. That means it shows white to seaward and red and green in different sectors extending in an angle of arc from the coastline to around 47deg to seaward. It is essential that the colours are clearly distinguishable from each other. Thus the white light is white - not red,orange or yellow and is clearly seen as white. When at sea and approaching the ness, if you see a red light you are in the danger zone and must alter course to seaward until you can no longer see the light. The flash of white light at every five seconds identifies that light from every other light around the UK coast. Note, it is a flashing not occulting light. The red light is much lower than the white (it's at approx 13m) and does not flash. It is a steady light - as is the green which shows to the north. If mariners get this wrong, i.e. mistake the identity of the light or ignore the red sector light, they end up either going aground, going off course or both. Get hold of any nautical chart and any nautical alamac such as Reeds for details of the sectors the lights are seen in. If Halt saw a red light then no matter what other factors are being played with it was NOT the lighthouse. End of. The lighthouse is there for reason, not just to decorate the coast.H: that's a strange, small, red light
