How to fix this problem? ios touch screen?

My code for a ray that picks up an object when the screen is touched works well, but there is one problem, the screen is generally always being touched. Is there a way, so that it doesn’t count the fingers already touching the screen? Thanks a ton,

My script:

#pragma strict

function Start () {

}
var guiray : GUIText;
var flashlight : GameObject;
var flashlightdesk : GameObject;
function Update () {
      var hit : RaycastHit;
var ray = camera.ScreenPointToRay (Vector3(200,200,0));
     Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
       var fwd = transform.TransformDirection (Vector3.forward);
if (Physics.Raycast(ray, hit, 100)){
     //   print ("There is something in front of the object!");
  //  var fingerCount = 0;
 //   for (var touch : Touch in Input.touches) {
 //       if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled)
   //         fingerCount++;
 //   }
  //      if (fingerCount > 0){
  //      print ("User has " + fingerCount + " finger(s) touching the screen");
 if(hit.collider.gameObject.CompareTag("light")) {
guiray.text = "Pick Up Flashlight"; 
    if (Input.touchCount > 0) {
   //place pick up code here!
   flashlight.gameObject.active = true;
      //flashlight.gameObject.enabled = true;
   flashlightdesk.gameObject.active = false;
}
}
else {
guiray.text = "";
}
}
}

I am actually curious to if there is a preferred way for single touch commands for phones. As of now I am still just using what I used for my last PC project:

if (Input.GetButtonDown (“Fire1”))

As of now I haven’t seen any reason to actually use the touch method. Maybe I am missing something?
