Showering has never been more fun than with this LED color changing showerhead. Simply attach the chrome plated showerhead to your existing standard shower hose and see the water change color according to the temperature. Never again will you have to step into a shower that's either too hot or too cold. If the water is hot it will turn red; warm, pink; cool, blue; and cold, green. And what's more the LED lights are illuminated by the force of the water so absolutely no batteries are required.
