Scania truck taillight replacement part card 420, left side or right side plastic lamp housing for heavy goods vehicle HGVs and commercial vehicle maintenance repairs
Scania Card 420 Replacement Taillight: Left or Right Side Plastic Housing for HGV Maintenance

This replacement taillight is designed for Scania commercial vehicles requiring a card 420 compatible lamp unit. It serves as a direct fit component for maintenance workshops, fleet managers, and repair specialists working on Scania trucks and heavy goods vehicles (HGVs). The product is identified by its accessory number LZ-S-077, which aids in accurate parts sourcing and ordering. With a specified service life of 10,000 hours, this unit provides a practical solution for restoring essential rear lighting, which is crucial for vehicle roadworthiness and safety compliance on UK roads. The lamp is constructed with a plastic housing and is available in two distinct styles to suit either the left-hand or right-hand side of the vehicle.
Features and Construction

The Scania taillight is built to serve as a replacement part within a specific vehicle ecosystem. Its primary features are defined by compatibility and a stated operational duration, offering a functional component for repair scenarios.
Material and Build
The lamp housing is made from plastic, which forms the external shell of the taillight unit. This material choice is common for vehicle lighting components, providing a housing that is moulded to the required shape. The source text does not provide further details on the type of plastic, internal reflector design, lens material, or the bulb or LED specifications included within the housing.
Size and Practical Fit
This taillight is offered in two specific styles: 'On The Left' and 'On The Right'. This indicates it is a side-specific component, meaning the correct version must be selected based on which side of the vehicle requires replacement. The product is listed as a single unit, packaged individually. No physical dimensions, mounting hole patterns, or connector types are detailed in the provided source information, so verification of physical fit against the existing unit is recommended prior to purchase.
Uses and Placement

This component has a clear, singular use case within the commercial vehicle sector. It is not a universal or multi-purpose item but a targeted solution for a specific maintenance need.
Event or Professional Use
This taillight is intended for professional vehicle maintenance and repair. Its primary application is within workshops servicing Scania trucks, fleet maintenance operations, or for owner-operators conducting their own repairs. The 10,000-hour service life rating provides a benchmark for expected performance, which can be useful for fleet maintenance scheduling and parts inventory planning, helping to minimise vehicle downtime.
Everyday Home Use
While the product could be used by a knowledgeable individual for personal vehicle repair, its application is inherently specialised. It is specifically for Scania commercial vehicles, not for cars, vans, or other non-compatible machinery. Successful installation requires technical knowledge of vehicle electrical systems and the specific fitting procedure for the target Scania model.
Benefits and Buying Value

The value of this product lies in its role as a direct, compatible replacement part, restoring a legally required vehicle function rather than offering aesthetic or performance upgrades.
Reuse and Low Maintenance
As a replacement part, the core benefit is the restoration of the taillight's original function. The 10,000-hour service life indicates a expected period of operation before potential failure, which supports planning. The product itself, once installed, requires no routine maintenance beyond the standard checks applied to any vehicle lighting system, such as ensuring it remains clean and functional.
Why Choose This Product
This product should be chosen when a Scania truck's existing card 420 taillight is damaged, failed, or requires replacement. The key reasons are its stated compatibility with Scania vehicles, the clear accessory number (LZ-S-077) for error-free ordering, and the availability of both left and right side options. It provides a factual, no-frills solution focused on getting a specific vehicle back into safe, compliant operation.
