During the refurbishment between the 1st and 2nd floor, the "Radio City 96.7" lettering was added which illuminates yellow during nighttime. Several other lights were added into the base of the crows nest structure which illuminate all day and periodically change colour. During Christmas time a beam of light is fired at the base of the tower. The 2nd floors windows are often illuminated at night with a particular colour to mark certain events. A red aircraft warning light sits on top of the Beacons advertisement framework to warn planes of its height at night.
