Disabling Multiple light sources in 1 script.

I am trying to make a lightswitch script. I can make the script disable one light source but how do I disable multiple lights (That I can drag and drop) without adding tags.

Aids Code Here (DOESN’T WORK)

var Source1 : Light;
var Source2 : Light;
var Source3 : Light;
var TurnedOn : boolean = true;

function Start () {
	Source1 = GetComponent.<Light>();
	Source2 = GetComponent.<Light>();
	Source3 = GetComponent.<Light>();
	Source2.enabled = true;
	Source1.enabled = true;
	Source3.enabled = true;
	TurnedOn = true;

}

function Update () {
	if (Input.GetKeyDown(KeyCode.E) && TurnedOn == true) {
		TurnedOn = false;
		Source2.enabled = false;
		Source1.enabled = false;
		Source3.enabled = false;
	}
	if (Input.GetKeyDown(KeyCode.E) && TurnedOn == false) {
		TurnedOn = true;
		Source2.enabled = true;
		Source1.enabled = true;
		Source3.enabled = true;
	}
}

The fixed code in C# using an array and foreach loop

    public Light[] lights;

    private bool TurnedOn = true;

    public void Update()
    {
        if (Input.GetKeyDown(KeyCode.E))
        {
            if (TurnedOn)
            {
                TurnedOn = false;

                foreach (Light obj in lights)
                    obj.enabled = false;
            }
            else if (!TurnedOn)
            {
                TurnedOn = true;

                foreach (Light obj in lights)
                    obj.enabled = true;
            }
        }
    }
