Target target : Name of light entity or entities to turn on or off depending on received trigger type: 'Off'- turn light off, 'On'- turn light on, 'Toggle'- toggle light.

OnDestroy Function ondestroyfn : Name of the function to use from already parsed .as script files when entity is destroyed (killed) in any way. If the function belongs to namespace, you must use prefix with the namespace name (e.g. mynamespace::MyFunction) for the keyvalue.

Name targetname : Set name of global_light_control so other entities can trigger it to do both: toggle lights specified in "Target'" field AND apply custom appearance to all lights on map with custom appearance set to 'Normal'. Every trigger use-type works uniformly. Signal type is interpreted by lights specified in "Target". Can be multiple triggered for "Target" lights but globally applied light styles will be applied once and cannot be reverted (you need another global_light_control with normal style to reset this). Can be kill-targeted but effects done by this entity are not reverted.
