How Can I enable and then disable a light in unity after a certain time?

Question

First off, I would just like to say that I am new to using Unity Answers (this is the first question I've asked), so if there is anyway I can improve this question, please let me know, thanks!

I am attempting to make a weapon system for my game. I have a point light on the end of the gun with a "LightManager" script attached to it. When my gun is fired, I get a reference to that script in my gun controller script, and call the MuzzleFlash() function.

Here is my code so for my light manager class so far:

 public class LightManager : MonoBehaviour {
 
     Light light;
 
     // Use this for initialization
     void Start () {
         light = GetComponent<Light> ();
         light.enabled = false;
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     public void MuzzleFlash() {
     
         light.enabled = true;
 
         // After 0.5f seconds
 
         light.enabled = false;
 
     }
 }

In my MuzzleFlash function I enable and then disable a light, but right now it does this all in one frame. How would I be able to enable it, wait X amount of time, and then disable the light?

The simplest way would be to use a coroutine like this

 public void MuzzleFlash()
 {
     StartCoroutine(MuzzleFlashCR());
 }
 
 private IEnumerator MuzzleFlashCR()
 {
     light.enabled = true;
     yield return new WaitForSeconds(0.5f);
     light.enabled = false;
 }
