I need it for this script which will allow the user(developer) to select what lights and how many (why I need that drop down) to turn off which then plays a SFX to simulate say a power outage or something. heres the script.

var sound: AudioClip;
var action: boolean;
var done: boolean;

function Start(){ 
 action = false; 
}


function OnTriggerEnter( other : Collider ) {
   if(other.tag == ("Player")){
     action = true;   
   }
}


function Update(){
 if(!done){
 if(action){
  light.enabled = !light.enabled;
  audio.PlayOneShot(sound);
  done=true;
  }
 }
}


@script RequireComponent(AudioSource)

I might be wrong but I don’t think you can based on your images provided, which they seem to me that they are from the inspector, your users are not going to be able to access the inspector from their end. Thus, I would suggest you to create some GUI (text or texture) element with all the possible choice the user can choose from (with a script). Then use script referring to pass it onto your script above.
