Heavy Duty Truck SHACMAN Cab Electrical System / Interior & Welcome Lighting System Parts DZ97189721333/21334 Cab Welcome Lamp Left Right For X3000

The DZ97189721333 and DZ97189721334 Welcome Lamps are cab lighting components designed for compatible SHACMAN X3000 heavy-duty trucks, with the two part numbers corresponding to the left and right installation positions. The lamps form part of the truck's cab electrical and welcome-lighting system and are used to provide localized illumination around the cab entry area when the driver or passenger approaches or accesses the vehicle. Their projection-light design also allows a specific lighting pattern to be displayed around the vehicle, making the component more than a conventional interior lamp. For heavy-duty trucks used during night transportation, roadside stops, loading operations, and other low-light conditions, localized cab-entry lighting can make the area around the access point easier to see while also maintaining the intended appearance of the vehicle's lighting system. DZ97189721333 is identified as the left-side version, while DZ97189721334 is the right-side version, so correct side selection is important when replacing only one damaged lamp. SHACMAN parts information also distinguishes these part numbers from other similar welcome-light numbers by their projection pattern, meaning buyers should not select a replacement solely according to external appearance. These components are suitable for SHACMAN X3000 cab lighting maintenance, welcome lamp replacement, and commercial truck spare parts supply. Before ordering, buyers should verify the OEM number, left/right position, connector configuration, mounting arrangement, and projection pattern against the existing lamp.
