Why is my point light not working? Invisible Sphere appears instead of the light bulb.

When I place a point light into my scene the point light appears as a Sphere NOT A LIGHT BULB!
Why is this happening?

The inspector panel still has the same components that a point light would have.
However, when I change the intensity, radius, color, etc… Nothing works or has an effect to the scene.

I haven’t updated my unity, is this the reason?
I’m afraid if I update unity it will have an effect on my game.

HELP!
What’s going on?
What can I do?

Thank you for taking the time to look at my problem!
If you can help I would very much appreciate it.

I checked here, i saw a light bulb.

OK try this.

And an empty game object in the game and then from ‘Add components’ choose rendering and in there select ‘Light’. may be, may be this will work.

reply please and tell what happen.
