Unity Rotate Raycast on Quaternion

Hi, sorry, I am still a beginner, but I need some help.

I want my player to have a raycast for my flashlight, and when this ray hits the enemy, I want it to slow the enemy down. I want the raycast rotation to be player.transform.rotation, but that variable is a Quaternion, and the field in the raycast requires a Vector 3, how can I rotate the raycast with a quaternion smoothly?

BTW this script is attached to the enemy.

public class MogiAI : MonoBehaviour {

	public GameObject player;

	public GameObject flashlight;
	public float MovementSpeed = 2;

	public bool IsMoving = false;

	bool Triggered = false;

	private healthscript healthy;

	// Use this for initialization
	void Start () {
		healthy = player.GetComponent<healthscript>();
	// Update is called once per frame
	void Update () {
		RaycastHit hit;
		Ray lighter = new Ray (flashlight.transform.position, flashlight.transform.rotation);

		if (Physics.Raycast (lighter, out hit, 10.0f)) {
			Debug.Log ("finally");
		if (player.transform.position.y < 8.4) {
						IsMoving = true;
				} else {
			IsMoving = false;
		if (IsMoving == true){
			transform.position = Vector3.MoveTowards (transform.position, player.transform.position, MovementSpeed * Time.deltaTime);
		transform.LookAt (player.transform.position);
		if (Triggered == true) {
			healthy.health = healthy.health - 0.5f;

	void OnTriggerEnter (){
		Triggered = true;

	void OnTriggerExit (){
		Triggered = false;


Sorry, I found out the way to do it on my own. I put a raycast script on the player and did it all in reverse! It turns out you cant put a raycast and rotate it properly on another object.
