Airport fog landing lights missing

Hi all:I am writing this because I seem to have lost the landing fog intermitent lights of an airport (GCXO). I am almost sure that some time ago the red and white poles of the attached screenshot had an intermitent illumination for fog approaches (I don't know the technical name for that). The problem is that I may have changed something and now I can't seem them.So my question is in which part of an scenery lies the ability of showing that type of lights to try to guess what I can have missing on it.Thanks.
