FlashLight Animation if energy<10??

Hey everyone:), I have a working script for my FlashLight that makes it run out of energy en a while. I'm not good at scripting but i have this idea of adding an animation to the end of the life of the flashlight (It will flicker, low intensity, etc. The animation is done so thats not a problem;)) Is it possible to add to this script an event that tells something like: If energy<10, animation.Play()??? Please Help:)

The Flashlight Script:

 //Name this script Flashlight and attach it to your player for instance
  
 var lightSource : Light; //Connect the light source in the Inspector
 var shootSound:AudioClip;
 static var energy : float = 100; //The energy amount of the flashlight
 static var turnedOn : boolean = false; //Boolean to check whether it's turned on or off
 private var drainSpeed : float = 9.0; //The speed that the energy is drained
  lightSource.enabled = false; 
 function Update () {
     if (Input.GetKeyDown(KeyCode.F)) ToggleFlashlight();
         
 }
 
 //When the player press F we toggle the flashlight on and off
 function ToggleFlashlight () {
    if(energy>1){
        turnedOn=!turnedOn;
       audio.PlayOneShot(shootSound);
     if (turnedOn && energy>0) {
        TurnOnAndDrainEnergy();
     } else {
        lightSource.enabled = false;
     }
     }
 } 
  
  
 //When the flashlight is turned on we enter a while loop which drains the energy
 function TurnOnAndDrainEnergy () {
     lightSource.enabled = true;
     while (turnedOn && energy>0) {
        energy -= drainSpeed*Time.deltaTime;
        yield;
     }
     lightSource.enabled = false;
 }
  
 //This is called from outside the script to alter the amount of energy
 static function AlterEnergy (amount : int) {
     energy = Mathf.Clamp(energy+amount, 0, 100);
 }
