Purpose and body fitment

The presented taillight has been designed specifically for the rear right side of the C140 series coupé body. Its placement in the rear zone ensures proper vehicle visibility for drivers behind you, as well as compliance with the factory lighting system. The lamp's construction is adapted to the body lines, ensuring an even fit with the fender and trunk lid after installation.

The original Mercedes origin means maintaining the correct optics, light distribution, and compatibility with the vehicle's electrical system. This is particularly important for high-end vehicles, where stable lighting parameters affect both safety and the consistent appearance of the rear bodywork.

Function in the Rear lights and brake lights system

The lamp belongs to the Rear lights and brake lights group, responsible for signaling the vehicle's position, braking, and – depending on the configuration – turning. A properly functioning component in this zone:

• increases the clarity of light signals for other road users,
• reduces the risk of collision during braking and driving in low visibility conditions,
• maintains the vehicle's compliance with external lighting regulations.

For C140 models, using an original right-side taillight allows for a uniform appearance on both sides of the vehicle, without differences in color or light intensity between the left and right sides.

Characteristics of the used component

The offered lamp is a used part, which allows for an economical repair of the lighting system while maintaining the factory design. In practice, this means:

• preservation of original mounting points,
• compatibility with factory electrical harnesses,
• possibility of installation in place of a damaged lamp without bodywork modifications.

Choosing a used OEM component is often preferred for repairs of classic vehicles and youngtimers, such as the C140, where stylistic consistency and compliance with the manufacturer's original design are valued.

Benefits of using the original Mercedes C140 taillight

Using an original right-side taillight in a Mercedes C140 provides a number of practical benefits:

• Factory fit – no need for modifications to mounts or the electrical installation.
• Consistent optics – maintaining a uniform appearance and light intensity on both sides of the vehicle.
• Operational safety – proper signaling of braking and vehicle position in road traffic.

For C140 owners, this is a solution that allows for the restoration of full rear lighting functionality while preserving the character of the original Mercedes design.
