This very stylish designer waterfall faucet changes its LED light color with the water temperature. Blue for cold, green for medium and, you guessed it, red for hot. For the LED light no battery is needed. The power for the light comes from the water flow. The only switch you have on this beautiful faucet is for hot-cold water. Because of the automatic sensor, the water starts to flow as you put your hands under the faucet. 
Beautiful, functional and cool. Not much more to say.
