LED lights, make your own?

EDIT: The creative juices are now flowing..... so remember there was something on here about lightening things through drilling small holes in it, how about even smaller ones..... lots of tiny holes and you could simply rip up some old christmas decoration with a lighting system and fibre optic cables and you could make a sparkling seatpost.p
i like it!

or just simply have an integrated light in the seatpost, cut out a small window and shove a light inside
