A Self Powered LED Shower Head Changes Color By Temperature
The LED Shower Head provides a colourfull notification when your water temperature reaches above 89° F/32° C.
When the water temperature goes a bit high, the colour of the LED light changes from blue to red, letting you know that now the temperatue of water in your shower is ready or warm and you won’t freeze to death. It is even pretty eco-friendly. It doesn’t need batteries for power, as the water pressure pushing built-in turbines provide all of the energy it needs. You can get it just for 45$ from wowcoolstuff.com
