When the average person wants to check the water temperature coming out of the faucet, they usually stick their finger under the running water, right? Well,in this day and age, why should anyone be bothered with the old fashion way, when you can do it the high tech way? This nifty gadget is called The Temperature Controlled Faucet Light. Here’s how it works. When the water is hot (89 Degrees Fahrenheit), the water turns red. When it’s cold, (under 89 Degrees) it’s blue. Pretty cool, huh? (No Pun Intended). It’s both fun and functional! And pretty handy for older people. It works on most USA faucets, and includes adaptors for 95% of most manufacturers. Sweet!
