How can I see satellites at night?

The title. How can I with my bare eyes see satellites fly by at night? Is it the sun's reflection that I see or are the satellites equipped with their own lights?

edit: Ok. I wasn't really clear. I've seen the satellites at night and what I'm asking is how it is POSSIBLE to see them with my bare eyes.

You are seeing reflected light. You'all also notice that the intensity of the light goes cyclically up and down; the rate at which the albedo changes is the rate at which the satellite spins around it's axis.
