The Runwaylights of the V4 Simwings Addons (Malaga, Menorca, Mallorca and Ibiza) use the same custom Runwaylights (no default files are used here), as they was used for FSX/P3D V3 before without any reports like this here. When the lights are ok at the first load of the scenery, it need to be explained more in detail, what is done by the "second load" of the scenery. What is a second load?
