Temperature-Sensing LED Faucet Light Attachment

A faucet light that reads the water temperature and lights the stream, all on its own.

This attachment adds a lit, color-changing stream to your kitchen or bathroom faucet and comes on automatically when the water flows. Made from durable ABS plastic, it holds an internal micro-generator that powers the LEDs from the water itself, so there are no batteries and nothing to plug in. A temperature sensor shifts the color, typically cycling blue, green, and red for cooler, moderate, and hotter water.

Why we picked it

• Temperature at a glance - The color-changing LEDs help you read the water before you reach in.
• No batteries needed - An internal generator runs the light off the water flow, so there's less to maintain.
• Simple to fit - A threaded connector and built-in aerator make setup quick on most standard faucets.

Good to know

The attachment has an external thread of about 0.93 inch (23.5 mm); the included adapter has an internal thread of about 0.87 inch (22 mm). Compare your faucet thread size and type before ordering. The integrated aerator keeps a smooth, steady flow while supporting more efficient water use. It works on indoor or sheltered outdoor faucets. If flow or light weakens, clean the aerator to clear mineral buildup and check that the connector is tight.

Common questions

Q: Does it need batteries or power?
A: No. An internal generator powers the LEDs when water flows through.

Q: How does the color change?
A: A built-in sensor sets the LED color to the water temperature, usually showing different colors for cooler, moderate, and hotter water.

Q: Will it fit my faucet?
A: Compare your faucet with the attachment's 0.93 inch (23.5 mm) external thread and the included adapter's 0.87 inch (22 mm) internal thread. These measurements refer to the two different parts.

Q: What if the flow or light gets weak?
A: Remove it and clean the aerator to clear buildup, then make sure the connector is tight and leak-free.
