Ready for a quick shower… wait, you may want to check out the water if the temperature is just right. Most of us will stretch out an arm to feel the water temp, but geeks… hey we’ve got something else. Check out the “LED Shower”. If the water that’s coming out is cold, it will auto display the blue led, if it’s hot, the red led lights up.

Features:

• Blue light means the water is cold; Red light means it has warmed up to 89° F (32° C).
• No batteries needed – powered by internal turbine.
• Installs in minutes to standard (3/4″) shower pipes.
• Includes a Flow Regulator that limits maximum water flow to 2.5 gallons per minute at 80 psi (might affect Shower Light performance depending on your water pressure).
• Approx. 4″ in diameter

Sold online by ThinkGeek.com for US$39.99.
