Detailed Description

Dorman 923-251 is built as an OE-style replacement for the center high mount stop light used on specific Mercedes-Benz CLK vehicles. The assembly is designed to match the original lamp’s shape and mounting points so it installs in the factory location and restores the rear brake light signal. This part number, 923-251, is a fitment-based replacement for 1998-2009 Mercedes-Benz CLK applications, including CLK320, CLK55 AMG, CLK350, CLK500, CLK280, CLK550, and CLK63 AMG models.

The lamp uses LED bulb technology and a red lens to provide the correct rear brake light appearance for the vehicle. It is supplied as a plastic third brake lamp assembly with bulbs included. Mounting hardware and wiring harness are not included, so reuse of existing vehicle components is required where applicable.

This part cross-references Mercedes-Benz OE part number 2098200156 for the same application.

What It Helps Solve

• Cracked or broken third brake light housing
• Dim, failed, or intermittent center brake lamp operation
• Water intrusion or lens deterioration at the rear roof-mounted lamp
• Restoring proper brake light visibility on Mercedes-Benz CLK models
• Replacing a worn factory center high mount stop light without dealership sourcing

Installation Notes and Tips

Verify vehicle year, model, and trim before ordering. This assembly is made for the factory center high mount stop light location on the listed Mercedes-Benz CLK vehicles. Because mounting hardware and the wiring harness are not included, inspect the existing connectors, seals, and fasteners before installation. Confirm the lamp seats correctly and that the brake light functions properly after installation.

Quality Assurance

Dorman manufactures this replacement as a reverse-engineered OE-style part for the specified applications, with fit and function matched to the original assembly.
