For loop is being totally ignored

I've posted a script I'm using in a game, the script essentially draws a laser beam from a laser gun to a target using a line renderer and then instantiates some point lights along the beam's path to give it a glow effect on nearby objects. It's a little lengthy and I'm only needing help on a small part of it, but to avoid ambiguity I've just included the whole thing. At line 50 I have a for loop that is supposed to be in effect if the variable "firing" is true, which I currently just turn on and off manually in the editor. Everything in the script works fine, but for some reason the game totally ignores the for loop at line 50. I don't get any error messages, and I've even tried commenting out the rest of the loop except for the print line for debugging purposes, and it never prints that line, no matter what.

I'm sure it's not a matter of the "noOfLightsNeeded" variable being zero or anything like that, I've already made sure it reaches a positive integer greater than 1. Any ideas?

 var lineRenderer : LineRenderer;
 var laser : GameObject;
 var target : GameObject;
 var laserMaterial : Material;
 var firing : boolean = false;    // Is laser firing?
 var laserGlowLight : Light;        // Light prefab for glow effect
 var distToTarget : float;
 var noOfLightsNeeded : int;
 var currentNoOfLights : int;
 private var i : int = 0;
 
 function Start () {
 
 }
 
 function Update () {
 
     if (i == 0)        // Initial instance of line renderer at game start. For some reason, function Start () wasn't working.
     {
         lineRenderer = gameObject.AddComponent(LineRenderer);
         lineRenderer.material = laserMaterial;
         lineRenderer.castShadows = false;
         lineRenderer.receiveShadows = false;
         lineRenderer.SetWidth(0.2,0.2);
         lineRenderer.SetVertexCount(2);
         i = 1;
     }
 
     if (firing)        // Enables laser if firing.
     {
         lineRenderer.enabled = true;
         lineRenderer.SetPosition(0,laser.transform.position);
         lineRenderer.SetPosition(1,target.transform.position);
         distToTarget = Vector3.Distance(laser.transform.position, target.transform.position);
         noOfLightsNeeded = Mathf.Round(distToTarget);    
         
         if (noOfLightsNeeded > currentNoOfLights)        // Adds lights along the beam as necessary
         {
             Instantiate (laserGlowLight, transform.position, transform.rotation);
             currentNoOfLights++;
         }
         if (noOfLightsNeeded < currentNoOfLights)        // Removes lights along the beam as necessary
         {
             
             GameObject.Find("Laser Fire Glow(Clone)").GetComponent(Laser_Glow_Destroy).exists = false;
             currentNoOfLights--;
         }
         
         for (var q = 1; q == noOfLightsNeeded; q++)
         {
             print ("For loop works.");
             var pointAlongRay : Vector3;
             var ray : Ray;
             var hit : RaycastHit;
             var direction : Vector3 = laser.transform.position - target.transform.position;
             if (Physics.Raycast (laser.transform.position, direction, hit))
             {
                 print ("Working on Point "+q+".");
                 Debug.DrawLine (laser.transform.position, hit.point);
                 pointAlongRay = ray.GetPoint(q);
                 GameObject.Find("Laser Fire Glow(Clone)").transform.position = pointAlongRay;
             }
         }
     }
     if (firing == false)        // Disables line renderer.
     {
         lineRenderer.enabled = false;
         noOfLightsNeeded = 0;
         if (currentNoOfLights > noOfLightsNeeded)
         {
             GameObject.Find("Laser Fire Glow(Clone)").GetComponent(Laser_Glow_Destroy).exists = false;
             currentNoOfLights--;
         }
     }
