Indicator Lamp
Mack

Premium indicator lamp designed for use in the cab or exterior lighting systems of Mack trucks. The lamp employs a durable enclosure and high-intensity LED or filament technology to deliver bright, unambiguous signals in daylight and at night. With robust sealing and vibration resistance, it remains reliable in the face of constant engine heat, road spray, and rough roads. The unit includes standardized electrical connections and mounting clips that fit common dashboards, switches, and external housings, enabling quick swap-outs during routine maintenance. The lamp's color, brightness, and duty cycle are selected to meet OEM indicator expectations, providing clear status cues for engine, electrical, or chassis systems. A low current draw translates to less strain on the vehicle's electrical network, while extended service life reduces replacement intervals. For installers, the component is straightforward to connect and test with standard diagnostic tools, helping technicians verify function quickly. As with all our offerings, we verify compatibility with the latest Mack specifications. Source One Parts Center delivers dependable, fleet-ready options.
