Light extenders are fairly common in the UK - not fibre optic, but basically they look like if silvery tubes connected to a glass dome on the roof. Fairly common when a house extension leave a hall without a window.

They work on the principle of total internal reflection. Same as a fiber optic cable. But they eventually leak so cheap LEDs it is.
