Those aren't lights. They are light *guides*. Much like waveguides for
RF frequencies. Think of them as fat fibre optic cables. 

You still need a light source somewhere, but you can have a lot of
distance between the source and the radiant exit point.

Wikipedia has nice pages on larger scale of this:
