Need a little extra light in the shower? Worried that the power will go out leaving you wet, cold and vulnerable to psycho attack? Sylvania's Ecolight may be just what you are looking for.

The Ecolight attaches to just about any standard showerhead and it features a LED light that is powered by the running water—so you never need to deal with batteries. It also features an LED temperature ring that turns blue when the temperature is under 78 degrees Fahrenheit and red when it is above 105.8 degrees. So, your protection here is three-fold: psycho attack, shrinkage and burns. Not bad for $40. [Sylvania via Luxury Housing Trends via OhGizmo]
