Flashlight Blink?

Good Evening,

Currently I’m working with flashlights. In my scene, I have a basic First Person Controller with a spotlight parented to the player camera (Main Camera.) I was wondering if there is anyway to make the flashlight blink on and off rapidly once every 60 seconds (even intervals.) If anybody could help me out with this, I would seriously appreciate it!!

using UnityEngine;
using System.Collections;

public class FlickerLight : MonoBehaviour 
{
	float waitTime;
	float offTime;
	bool on = true;

	void Start()
	{
		StartCoroutine(Flicker());
	}

	IEnumerator Flicker()
	{
		while(true)
		{
			//Change waitTime values as desired.
			//If you don't want random, just use an int: Example - Set at declaration: float waitTime = 60;
			waitTime = Random.Range (3, 6);

			//How long to disable light component.
			offTime = Random.Range (0.001f, 0.05f);
			light.enabled = false;
			yield return new WaitForSeconds(offTime);
			light.enabled = true;
			yield return new WaitForSeconds(waitTime);
		}
	}
}
