The Temperature Sensitive LED Shower Light ($45) is a cool new high-tech showerhead that makes water glow bright blue if the water is cool or bright red if the water is hot(89° F/32° C) automatically using super bright built-in LEDs. Simply install on any standard shower pipe, turn on the water and watch in utter amazement. It automatically turns on or off based on water flow through its internal turbine and since you will be playing with it constantly and showing it off to everyone, it also has a built in Water Flow Regulator so the water flow does not exceed 2.5 gpm at 80 psi. Best of all, since it provides a unique visual indication of water temperature, it makes it safer for children, older people (and you) from getting burned by hot scalding water. (via The Green Head)
