I writed script but I can’t activate the gameObjects. This is my script ;

function OnTriggerEnter (col : Collider) 
{
	if(col.gameObject.tag == "LampTrigger") 
	{
 		(gameObject.tag == "First").active;
  	}
}

I guess what you want is the setActive() function. You are not activating anything in the script you posted.

function OnTriggerEnter (col : Collider) 
{
    if(col.gameObject.tag == "LampTrigger") 
    {
      if(tag == "First" && !gameObject.activeSelf) gameObject.setActive(true);
    }
}
