No electricity, batteries, or external power required—simply open the water source to activate the light. 360-degree universal rotation allows water to cover the entire sink, making sink cleaning easier, especially in cold weather. Temperature-sensing tricolor indicator changes color based on water temperature: - Blue when water temperature is 31°C or below (cold water) - Green when water temperature is between 32°C and 43°C (warm water) - Red when water temperature is between 44°C and 50°C (hot water) - Flashing red when water temperature exceeds 51°C, serving as a warning to prevent scalding Quality tested for reliable performance: each faucet light is thoroughly checked for leaks and proper function before shipment. Self-powered by water pressure: generates its own power through flowing water, eliminating the need for batteries or electrical power. Designed for safety, energy efficiency, and long service life. Equipped with a high-speed, strong magnetic motor that ensures consistent LED lighting under normal water pressure. Sealed inner core construction prevents rust and corrosion from prolonged water exposure, ensuring stable motor performance and durability.
