Shine with silver macbook?

I want to buy a Macbook Pro soon but I do not know if I should take gray or silver. A friend of mine said yesterday that the apple lights on the back of the laptop, but only with the silver version. However, I do not want to believe that right.

Can you tell me if it really shines or not, because if it shines, I'll get you silver version, otherwise Space Gray

The apple does not shine anymore, since 2016, if I'm not mistaken. And the case color does not matter.
