You must only redo my script.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PopUpLights : MonoBehaviour {
    void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {

        if (Input.GetKey("l"))
        {
            transform.localRotation = Quaternion.Slerp(transform.localRotation, Quaternion.Euler(290, 0, 0), Time.deltaTime * 5);
        }
        if (Input.GetKey("o"))
        {
            transform.localRotation = Quaternion.Slerp(transform.localRotation, Quaternion.Euler(0, 0, 0), Time.deltaTime * 5);
        }

    }
}
