How to show an array of custom objects in Inspector?

I can show one object, but not an array of them.

BasicLight in Inspector: (I want to show an array of these)

LightTube contains an array of BasicLights and looks like this: (This does not work, I want to show an array of four fields each)

How do I get an array of BasicLights to show the fields of each element (that we see in the first image)? I have also tried making a CustomPropertyDrawer (not shown here), but I haven't been able to get it to work with the custom inspector. Any suggestions?

Code is below.

BasicLight (a basic light, of which arrays will be made of in the inspector)

 [Serializable]
 public class BasicLight : MonoBehaviour
 {
     public bool isLightOn = false;
 
     public string name;
     public GameObject light;
     public float range = 30.0f;
     public float intensity = 1.5f;
 }

EditBasicLight (creates the GUI controls in Inspector)

 [CustomEditor(typeof(BasicLight))]
 public class EditBasicLight : Editor
 {
     public override void OnInspectorGUI ()
     {
         serializedObject.Update ();
         BasicLight basicLight = target as BasicLight;
 
         basicLight.isLightOn = EditorGUILayout.Toggle ("on", basicLight.isLightOn);
 
         EditorGUI.indentLevel++;
         basicLight.name = EditorGUILayout.TextField ("name", basicLight.name);
         basicLight.light = EditorGUILayout.ObjectField ("light", basicLight.light);
         basicLight.range = EditorGUILayout.FloatField ("range", basicLight.range);
         basicLight.intensity = EditorGUILayout.FloatField ("intnsity", basicLight.intensity);
         EditorGUI.indentLevel--;
     }
 }

BaseLight (LightTube inherits from this) (attached to the GameObject) (Other classes will extend this, hence the name ‘Base’Light.)

 public class BaseLight : MonoBehaviour
 {
     public bool on = false;
     public BasicLight [] lights;
 }

EditBaseLight (BaseLight Editor. Creates the GUI controls in Inspector) (But how do you get the array to show correctly)

 [CustomEditor(typeof(BaseLight))]
 public class EditBaseLight : Editor
 {
     public override void OnInspectorGUI ()
     {
         serializedObject.Update ();
         BaseLight baseLight = target as BaseLight;
 
         EditorGUIUtility.LookLikeInspector ();
 
         SerializedObject serializedObj = new SerializedObject (target);
         SerializedProperty lights = serializedObject.FindProperty ("lights");
 
         serializedObj.Update ();
         EditorGUILayout.HelpBox ("Default Inspector", MessageType.None);
         DrawDefaultInspector();
         serializedObj.ApplyModifiedProperties ();
     }
 }

LightTube

 public class LightTube : BaseLight
 {
 
 }

EditLightTube

 [CustomEditor(typeof(LightTube))]
 public class EditLightTube : EditBaseLight
 {
     public override void OnInspectorGUI()
     {
         LightTube lightTube = target as LightTube;
 
         base.OnInspectorGUI ();
     }
 }
