The LED faucet light that changes color based on water temperature

The DLAND RC-F03 Water Stream Multicolor LED Faucet Tap isn’t going to change any lives anytime soon, but it really is an awesome little device. It screws onto any standard bathroom faucet and water passes through it just like the cap on your faucet now. With this one, however, there’s an integrated LED light that shines blue if the water is cold, red if it’s hot, and green if it’s just right!
