Flashlight with Partical help

I am creating a Flash light, and I wanted to have dust particals show when the light was enabled, how do I do that? Using my flash light script?

 using UnityEngine;
 using System.Collections;
 
 public class FlashLight : MonoBehaviour
 {
 
     public bool FlashLightOn = false;
     
     void Start()
     {
  
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetButtonDown("FlashlightPower"))
         {
             if (FlashLightOn == true)
             {
                 GameObject.Find("Light").GetComponent<Light>().enabled = true;
                 FlashLightOn = false;
                 Debug.Log("Light On");
             }
             else
             {
                 GameObject.Find("Light").GetComponent<Light>().enabled = false;
                 FlashLightOn = true;
                 Debug.Log("Light Off");
             }
         }
     }
 }
