- They are easy to insert. Just drill a 3/16" hole in the layout and insert the 1mm fiber through the hole and then the base of the lamp, which should be a snug fit . Insert the fiber beneath the layout into the Lamplighter box. Each lamp comes with 4’ (~1.3m) of 1mm fiber optic to allow optimal placement in proximity to the Lamplighter box.
To change the ambiance / color, add a drop of translucent paint to the end of the fiber. As you are putting this onto the end of the fiber that is inserted into the Lamplighter, make sure the paint is dry prior to inserting the fiber into the Lamplighter box. See the video on how to do this. To create an old world look, I use the Tamiya X-26 Orange Translucent paint, however, you may use whatever paint you like or even a colored marker.
