84195521 tail lamp – Description

84195521 tail lamp is a precision-engineered replacement rear lighting unit designed for right-side applications, built to support stable illumination in long-haul route operation, regional distribution work, and low-light depot maneuvering. It is designed for compatibility with commercial truck rear lamp positions where cracked lenses, fogged housings, vibration damage, or intermittent output from burnt connector pins can create safety and downtime risks.

Designed as an LED tail lamp with an E-marked configuration and Vignal-type styling, this unit focuses on consistent light output and durability. The construction supports moisture ingress protection and weather resistance, while the housing geometry and mounting interfaces are developed around OEM dimensional tolerances for a secure fit. Technicians benefit from a sealed connector interface and stable mounting bracket alignment, helping reduce repeat workshop visits caused by loose connectors or water entry.

For service teams, the 84195521 tail lamp supports plug-and-play compatibility with the existing wiring harness, enabling fast replacement during scheduled fleet maintenance. Correct guide pin alignment and fastener seating help maintain a flush installation that protects the lamp edges from impact and road spray. This matters for trucks that run high-mileage service, where rear visibility and reliable signaling are essential for compliance and safer night operation.
