Abstract: A plumbing fixture is provided to monitor and dispense a fluid in an illuminated fluid stream. The fixture includes a sensor in or adjacent the fluid path for sensing a water condition, such as fluid flow, temperature, volume, or contamination. Processing circuitry couples with the sensor and generates a message indicative of the water condition. Activation circuitry activates a light source to present the message to a user of the plumbing fixture. For example, the activation circuitry may select particular colors, patterns, or intensity of the light to inform a user of a fluid condition. The light source directs its generated light beam into the fluid path to illuminate the fluid stream and a localized area. In a particular example, the monitoring and illuminating device is attached to a water faucet to illuminate a water stream and to indicate that the water stream is in a safe temperature range.
