When the Blue LED Faucet Lights came out I thought they were the coolest things to happen to faucets since actual plumbing. Well, they have been upgraded! The new Temperature Sensitive LED Faucet Lights not only illuminate your water a brilliant BLUE like before, they also turn it a fiery RED once the water temperature reaches 89°! Not only is this a cool water effect, it's also a great warning sign that the water is starting to get hot and is a great child safety feature. This same technology should be used on shower heads next.
