Indicator Lamp
Mack

An indicator lamp on the dashboard provides a visible alert when a system requires attention. In heavy-duty equipment, indicator lamps cover engine, braking, electrical, and fluid-monitoring statuses, enabling proactive maintenance before a fault becomes critical. This lamp is designed for vibration resistance, long service life, and clear illumination in cab lighting conditions, including daytime glare and night driving. The lens and housing resist moisture ingress and have sealed connections to minimize corrosion. Proper installation ensures correct illumination color coding, mounting height, and visibility from the operator’s line of sight. When a lamp illuminates, a driver can quickly assess the related subsystem, tie it to a fault code, and plan service to prevent downtime. Regular checks during pre-trip inspections confirm that all indicators function as intended and that the lighting remains legible in varying ambient conditions.
