Purpose and function in the vehicle

The tail light lamp holder has been designed specifically for the Mercedes W163 model family as a component of the rear brake light assembly. It is mounted in the rear area of the vehicle, where it is responsible for:

• maintaining bulbs in the correct operating position,
• ensuring proper electrical connection with the vehicle's wiring,
• maintaining the light beam geometry in accordance with the lamp design.

Thanks to its precise fit for this specific body generation, it minimizes the risk of leaks and mounting play that can occur with non-original solutions.

Construction and technical advantages

The holder serves as a support base for bulbs and electrical contacts in the rear brake light. The construction provides proper routing of current paths, which reduces voltage drops and improves lighting reliability. The arrangement of the bulb sockets is consistent with the original Mercedes design, which facilitates:

• quick bulb replacement without any additional modifications,
• maintaining the correct order and function of individual light points,
• seamless fitment to the original tail lamp.

As a component from the Main and center brake lights category, the holder directly affects vehicle visibility during braking, which translates into road safety.

Condition, fitment, and service application

The offered tail light lamp holder is a used part, sourced from vehicle dismantling, which allows for maintaining factory mounting specifications. This is a practical solution in situations where:

• mechanical damage to the housing has occurred due to a collision or corrosion,
• there are issues with intermittent brake light operation,
• it is necessary to replace the holder itself without the need to purchase a complete lamp.

Original Mercedes branding ensures compatibility with the electrical harness and factory connectors, which reduces the time required for installation and diagnostics.
