problem reflecting a ray

Hello,

I am having trouble reflecting a ray for a simple aiming system (ike a laser with one bounce on a rigidbody, no physic calculations or what so ever).

I kinda have it working but the angle is off. I am struggling with this for a day now so i think i need some extra eyes!

 using UnityEngine;
 using System.Collections;
 
 public class AimBeam : MonoBehaviour {
 
     public Transform ball;
     public LineRenderer lineRenderer;
 
     public float rayLength;
     public Vector3 reflectDirection;
 
     void Start () {
         ball = GameObject.Find("Ball").transform;
         lineRenderer = this.GetComponent<LineRenderer>();
     }
 
     void Update () {
         //Face Beam In Ball Direction
         transform.rotation = ball.rotation;
 
         //Draw Ray
         Vector2 rayDir = transform.TransformDirection (Vector2.right) * rayLength;
         RaycastHit2D hit = Physics2D.Raycast (transform.position, rayDir);
         Debug.DrawRay (transform.position, rayDir, Color.green);
 
         //Set LineRender Pos 0 & 1
         lineRenderer.SetPosition (0, this.transform.position);
         lineRenderer.SetPosition (1, rayDir);
 
 
 
         //CHeck if Ray hits Collider
         if (hit.collider) {
 
             Vector3 hitPoint = hit.point; 
             lineRenderer.SetPosition (1, hitPoint);
 
             //Draw Normal line
             Debug.DrawRay (hit.point, hit.normal*3, Color.blue);
 
             //Calculate reflect direction
             reflectDirection = Vector3.Reflect (rayDir, hit.normal);
             Debug.Log (reflectDirection);
 
             //Set reflect direction in lineRenderer
             lineRenderer.SetPosition (2, reflectDirection);
 
 
         } else {
             lineRenderer.SetPosition (1, rayDir);
         }
     }
 }

The problem has to be somewhere in this line "reflectDirection = Vector3.Reflect (rayDir, hit.normal);" What am i doing wrong? it has to be something with the input direction i think but i can't figure it out.

Thanks in advanced.
