Visualize the temperature of running tap water with this LED faucet light, which fits on most taps and an LED light will light up when you turn on the tap.
The LED Water Faucet Stream Light Temperature Sensor is extremely easy to install. All you have to screw on the faucet piece and use the internal thread adapter provided instead of a universal one. There are no external batteries or power supplies needed; once installed, the light piece does all the work itself.
The faucet's built-in thermometer measures how hot or cold the running water is and categorizes them into three colors: red for anything above 44 degrees Celsius, green for lukewarm (32°C - 43°C) and blue for cold. This would be a fun visual to add to any kitchen or bathroom -- the colorfully illuminating water tap will add a nice finishing touch to any sink.
