So does this mean that mean that my mouse is broken/defective? If so, is there anything I can do to fix it?

So today i bought the Tt esports Commander Multi-Light Gaming Gear Combo, and i'm a bit confused with the mouse. Everything is working fine but there's just 1 thing i'm not sure about. On the each side of the mouse, there's 3 swooping slots cut out. Is light supposed to come through these? Because for me it's not doing that. I've seen pictures of light coming through them, although it seems that's not the case for me. So my main question is,(mainly to people who have this combo), is there supposed to be light coming through it? For other owners of this, does it work for you? If so please tell me how. Please respond! Desertsand
