As well as the main, active lighthouse, Trekroner also has (or possibly had) a pair of disused range lights.  My photos of these are poor as I picked them up from other images - but, poor or not, I'm fairly sure that most of the sources have got these lights the wrong way around.  This light is listed in the Lighthouse Directory as the "Forfyr" (front light) and I have named it as such here.  However the google map link given in the Lighthouse Directory actually points to the other light of the pair (I have corrected the link on this page so that it points to the same light as that in the photograph).  There are two points that make me suspicious about the naming - firstly, I can see how the range could have worked had this been the front light; secondly this is the taller of the two lights which, conventionally, would make it the rear light.  In any even, I'm not sure that it matters all that much as there is some evidence that both of these disused lights were finally demolished in 2009, the year after this photograph was taken.
