Indicator lights are essential components in industrial and automation systems, providing visual signals to monitor equipment status, operational conditions, or alarms. Common types include LED pilot lights, stack lights, and panel-mounted indicators, available in various colors (red, green, amber, blue) and voltage ratings (12V, 24V, 120V, etc.). Key features include high brightness, long lifespan, energy efficiency, and robust housing for harsh environments. Typical products in this category include illuminated push buttons, rotary beacon lights, multi-segment tower lights, and explosion-proof indicators. These lights are widely used in control panels, machinery, and automated production lines for real-time status indication and fault alerts.
