Cant get sound play on input

 I dunno what Im doing wrong I wrote this toggle script to turn a light on and off but it wont play my sound along with the light. The sound plays on awake but not when i press the input. Im just trying to get work like the switch on a flashlight. 

heres the code:

 using UnityEngine;
 using System.Collections;
 
 public class headlight : MonoBehaviour {
 
     //light toggle on and off
     public Light light1;
     public AudioClip onswitch;
 
     private AudioSource source;
     //
     void awake ()
     {
         source = GetComponent<AudioSource>();
     }
     
 
     /// </summary>
 
     void Update () 
     {
         if (Input.GetKeyDown ("l")) 
             {
             
             light1.enabled = !light1.enabled;
             source.PlayOneShot(onswitch, 1F);
         }
     }
 
 
 
 
 
 
 
     }
