Info

Reworked for Factorio 2.0 API. Adds new settings for more flexibility.
Adds Space Age support, support for more buildings with a new type-based system, and adds user-customizable include/exclude filters.
Now has Per-Planet Configuration in its own additional GUI settings dialog.
Includes commands:
/HazardLightsRedux gui - opens planet-specific settings dialog, in case you want to disable both the GUI button and the Hotkey
/HazardLightsRedux legacy - toggles off/on the changes done in 18.1.10 to how lights and lightbulbs are positioned
/HazardLightsRedux uninitialize - wipes all created lights and lightbulbs
/HazardLightsRedux reinitialize - wipes and recreates all lights and lightbulbs

Notes

Compatibility with Even Pickier Dollies, and an included option to disable lights around power poles -- to be friendly with various Electric Pole Light mods.
Customizing colors may be a bit iffy, as they "blend" with the terrain the entities are on. It may seem that the colors are sometimes "off", especially if using lighter colors, like blue. To accurately customize the light colors, place refined concrete beneath the entities and adjust the runtime settings as desired.
Multiplayer not tested/don't care.
I generally do not care about other mods that add new content/entities/buildings to the game, so do not expect hard-coded compatibility or testing to come at any reasonable pace.
