trouble with toggling light on and off

I am working on a script where i have a spot light attached to a flashlight object, and i want to cut it on or off with the " o " button. i tried several different ways, until i searched the forums and found a method that i thought would work.( 1st commented block of code) the problem with that block of code is that it turns on or off all lights, and i just want to be able to toggle only the flashlight. i got it to work by using 2 different letters (o and p, as in the 2nd commented block of code, but that is not how i want it to work. anyway i tried a combination of the 2 commented blocks of code and i don't get any errors, but when i start the scene, the light is on, then when i press o the light goes off. but, when i press o again to turn it on, nothing happens except the console says " the light is off" which tells me that it is not returning to the start of the code... i am stuck now.... below is the code and the several other attempts that i tried. i'm still learning with difficulty........
thanks

Code (csharp):

1. // public var lightOnOff = light.intensity;
2.  
3. public var lightOnOff : boolean = true;
4.  
5. function OnGUI()
6. {
7.      GUI.Label (Rect (10, 10, 200, 20), "Use o to turn flashlight on or off");
8. }
9.  
10. function Update()

17.             Debug.Log("Light is on");
18.            
19.         }
20.         else
21.             light.intensity = lightOff;
22.             Debug.Log("light is off");
23.     }
24. }
25.

After

Code (csharp):

1. if(Input.GetKeyDown("o"))    {
2.  

add below line and check this out.

Code (csharp):

1. lightOnOff =! lightOnOff;

 

awesome UnityCoder, I would have never thought about that. thanks
