c# light off

How would i make it so that when i start the game the light is off and not on?

using UnityEngine;
using System.Collections;

public class LightSwitch : MonoBehaviour
{
	
	public Light Light;
	public GameObject goLightSwitch;
	
	public AudioClip SwitchOn;
	public  AudioClip SwitchOff;
	
	private bool _switchOn;
	private GameObject _upPosition;
	private GameObject _downPosition;
	
	private AudioSource _audioSource;

	void Awake()
	{	
	
		_upPosition = GameObject.Find ("UpPosition");
		_downPosition = GameObject.Find ("DownPostion");
		_audioSource = gameObject.GetComponentInChildren<AudioSource>();
			
	}
	
	void OnMouseDown()
	{
		 if (_switchOn)
		{
			_switchOn = false;
			goLightSwitch.transform.position = new Vector3(goLightSwitch.transform.position.x,
															_downPosition.transform.position.y,
														   goLightSwitch.transform.position.z);

		
			Light.enabled = false;
			_audioSource.clip = SwitchOff;
			_audioSource.Play();
	
			
		}
		
	
		else if (!_switchOn)
		{
			_switchOn = true;
			goLightSwitch.transform.position = new Vector3(goLightSwitch.transform.position.x,
															_upPosition.transform.position.y,
														   goLightSwitch.transform.position.z);

		
			Light.enabled = true;
			_audioSource.clip = SwitchOn;
			_audioSource.Play();
			
		}
	
	}
}

First change your Light Light to Light light Light is a class defined within Unity’s component system. May cause clashing of names.

Then from there in the Start function do the following light.enabled = false
also you could set the intensity to 0 or the radius/distance to 0 as well. Many ways to disable(turn on/off) the light. Check the doc for the methods.

void Start ()
{

		Light.enabled = false; 
	}
