Hot/Cold Faucet Indicator

The Faucet Light changes color based on the water temperature. It’s blue when the water is cold or simply turned “on.” When the temperature reaches 89°F, it changes to red alerting you that the water is getting hot. The Faucet Light turns an ordinary faucet into a streaming crystal blue light source. Simply turn on the water, and the internal pressure switch activates the light source. Turn off the water, and the light goes off.Works on most USA faucets and includes universal adapters for 95% coverage.
