Turret AI script off rotation

I have a javascript that runs an automatic turret... it controls the movement of the turret and a light that changes color depending if thee turret is engaged or not. Problem is the turret looks about 45 degrees to the right of the player. This has happened with a lot of scripts now and I have tried resetting various coordinates such as rotation of the turret, and the turret head and the player. Here's the code;

 var range : float = 75;
 var target : Transform;
 var damp : float = 2.5;
 var indicator : Light;
 function Update ()
 {
     target = GameObject.FindWithTag("Player").transform;
     var distance = Vector3.Distance(target.transform.position, transform.position);
     if(distance <= range)
     {
         indicator.light.color = Color.red;
         if(target)
         {
             var rotate = Quaternion.LookRotation(target.position - transform.position); 
               transform.rotation = Quaternion.Slerp(transform.rotation, rotate, Time.deltaTime * damp); 
               transform.LookAt(target);
         }
     }
     if(distance >= range)
     {
         indicator.light.color = Color.green;
     }
 }

How can I make it look about 45 degrees further to the left (or right, depending which way you look at it)?
