Finally PM made it: they provided the most suitable incredients for customizing a lighthouse. Last Saturday I went to my local toy store getting those: the new airport tower (which is available in Germany since September 1st). So here is my variant.
As you can see, I worked in the blinking light from the airport tower. To enlarge the lightning fire I covered the blinking light with a capsule from my two-component modelling glue putty. To diffuse the light I inserted a tracing paper to the capsule walls.
The glas cylinder around the fire is made from a plastic bottle which normally contains sparkling water; some white plastic stripes had been glued to it to make it looks like made of four sections.
The roof top is a plastic throw-away ice cream bowl. The railing is made from wire mesh (bought at my local DIY store); the top of the railing is a PM fire hose which I cutted lenghtwise (just one side) and put on the mesh.
Sorry for the poor photos, but I must admit, that I'm currently lacking a suitable background (sky) which is big enough to cover the complete background of the lighthouse -- so this is not my normal quality on providing new customizings
