As the BaseLightManagerComponent is handled at engine level, it is not possible to define additional enums for light types as they would not be processed by the engine via modding.

Certain vanilla vehicles, light helicopters, are already being forced to use weird light types for certain types of lighting (for example, reverse light type is being used for cabin lighting).

Some ideas for potential light Enum names:
Cockpit
Cabin
Floor
CustomLight1 etc.

The currently amount is too little!
