if a light is reserved, that means the base mod is not allowed to touch or change it in any meaningful/destructive way
reservations exist so other mods can say that this is their item and other mods should not change it
currently only the hazard-lights-selector uses this, all lights that did not change color, were at some point selected by a selector
this also gives us interesting information about the two buggy lights
specifically, the top one was caused by the selectors, and the bottom one was not
i will try and make an update to the selectors mod so that you can emergency delete lights that have no building for them
