I once heard about a fish with a built-in light, or something.

Lots of things down very deep bioluminesce. There simply isn't very much natural light at all in the depths of the ocean so it is used for everything from attracting prey (as in the anglerfish cheezyflier posted) to seducing mates to warning away competitors to communicating. Some even use it to navigate.
