Remember the LED Faucet, which transformed your bathroom faucet into an illuminated spectacle? Well, now you can have that same effect, with your shower!

The LED Shower Light from ThinkGeek installs onto any standard shower pipe. As you're running the water, the light will turn blue to indicate that the water is cold; once the temperature of the water warms up to about 89 degrees, the LED will shine red to indicate that it's time to hop in. Powered by an internal turbine, the LED Shower Light also includes a Flow Regulator that limits maximum water flow to 2.5 gallons per minute at 80 psi.

Your morning shower time never looked so geeky, for $39.99.
