Obstruction (more commonly known as aircraft) warning lights.
These are the red lights that can be seen from all around the area and above – these lights never change colour.
These illuminate the base of the Tower, including the back, bottom of the bows and either side and bottom of the legs.
These lights are white. This system is used alongside the show lighting system every day.
The show lighting are the lights we can control to change the main colour that the Tower is illuminated.
These are the lights we are referring to when we say ‘lighting the Tower’. They cannot be seen from as far away due to the nature of the lamps/light fittings used. The show lighting comes on 15 minutes before sunset and switches off at 11pm.
