How can i rotate the flashlight to the other side by 180 degrees ?

I tried to rotate it on the x then on the z but it’s always facing up.
The original position: The flashlight is facing back to the left.

When i check the checkbox in the Inspector on the Ik Active in the IK Control script i want the flashlight to rotate to the other side and to be facing to the right.

But this is what i’m getting when checking the checkbox on Ik Active: The flashlight is facing up:

The script:

using UnityEngine;
using System;
using System.Collections;

[RequireComponent(typeof(Animator))]

public class IKControl : MonoBehaviour
{

    protected Animator animator;

    public bool ikActive = false;
    public Transform rightHandObj = null;
    public Transform lookObj = null;

    void Start()
    {
        animator = GetComponent<Animator>();
    }

    //a callback for calculating IK
    void OnAnimatorIK()
    {
        if (animator)
        {

            //if the IK is active, set the position and rotation directly to the goal. 
            if (ikActive)
            {

                // Set the look target position, if one has been assigned
                if (lookObj != null)
                {
                    animator.SetLookAtWeight(1);
                    animator.SetLookAtPosition(lookObj.position);
                }

                // Set the right hand target position and rotation, if one has been assigned
                if (rightHandObj != null)
                {
                    animator.SetIKPositionWeight(AvatarIKGoal.RightHand, 1);
                    animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 1);
                    animator.SetIKPosition(AvatarIKGoal.RightHand, rightHandObj.position);
                    //animator.SetIKRotation(AvatarIKGoal.RightHand, rightHandObj.rotation);
                    lookObj.rotation = Quaternion.Euler(180, 0, 180);
                }

            }

            //if the IK is not active, set the position and rotation of the hand and head back to the original position
            else
            {
                animator.SetIKPositionWeight(AvatarIKGoal.RightHand, 0);
                animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 0);
                animator.SetLookAtWeight(0);
            }
        }
    }
}

I changed this line:

animator.SetIKRotation(AvatarIKGoal.RightHand, rightHandObj.rotation);

With the line:

lookObj.rotation = Quaternion.Euler(180, 0, 180);

Since i want to rotate the flashlight when it’s active and to rotate the hand.
But i tried: 180,0 ,0 ,0 then 0, 0, 180 and now 180, 0, 180 but the flashlight is pointing up not to the right.

( And when it’s not active is it logic the flashlight to be facing to the left like in the original screenshot ? I mean like in idle when not using the flashlight or i should change the flashlight position/rotation to something more logic then facing left ? )

Keeping it simple: How about you create an Empty GameObject, parent the flashlight to it, and rotate it locally?
