Fairy lights - Christmas lights

They would be a new light source, that would work with redstone. Made with colored glass, copper and redstone. We would also have several colors. The lights would emit about half a redstone lamp. They would be small, much smaller than a block. It would look a lot like a block of slime, but without texture. (would occupy about 5 pixels)

We would also have the addition of a "rope" or wire that could be used to hang the lights (the wire would also be used to pass the load to the lights) you could put them in rows. The wires could be connected from end to end. The lights could also be placed anywhere, however they will always need to be turned on by redstone.
