An indicator lamp with a buzzer is a combined signaling device used to provide both visual and auditory alerts in various applications. The indicator lamp typically uses an LED or bulb to display a specific status (e.g., power on, fault, or system activation), while the buzzer emits a sound to draw immediate attention. This combination is commonly used in industrial machinery, automotive dashboards, security systems, and household appliances to ensure that users are promptly notified of critical conditions, even in noisy environments or when visual cues might be missed. The integration of both light and sound enhances safety and operational efficiency.
