Genuine Mercedes Center High Mount Stop Light

Genuine Mercedes OEM Center High Mount Stop Lights

When a safety-critical lighting component on your Mercedes-Benz needs to be replaced, the source of the part matters. The Center High Mount Stop Light (CHMSL) — sometimes called the third brake light — is a federally mandated safety device mounted at the center top of the vehicle's rear. Its sole job is to alert following drivers the instant brakes are applied, and it has to do that job reliably every single time. For Mercedes-Benz owners, that means one thing: a Genuine Mercedes OEM part.

Why OEM Matters for the CHMSL

Mercedes-Benz vehicles are engineered to tight tolerances, and that philosophy extends right down to exterior lighting assemblies. A Genuine Mercedes Center High Mount Stop Light is manufactured to the exact specifications of the original unit that left the factory. This means the lens geometry, the mounting tabs, the wiring harness connector, and the light output characteristics all match precisely — no adapter brackets, no wiring workarounds, no guesswork.

CHMSLs are highly vehicle-specific, so it is always essential to verify the part is designed for your exact year, make, and model. With a Genuine Mercedes part, that verification is built into the part number itself. Each OEM assembly carries a Mercedes-Benz part number — such as those in the 099-906-63-04 or 167-906-33-02 families — that cross-references directly to the vehicle application, covering a wide range of model years from 2008 through 2026 across multiple Mercedes-Benz platforms.

Form, Function, and Finish

Some CHMSL replacements are full assemblies complete with housing and lens; others replace just the bulb — knowing which your vehicle requires is critical. Genuine Mercedes parts account for this distinction at the model level, ensuring you receive the correct assembly type for your specific vehicle, whether that is a sedan, coupe, SUV, or wagon. Genuine OEM units are also built to handle temperature extremes, moisture, and UV exposure — demands that are very real for a component mounted at the upper rear of a vehicle and exposed to direct sunlight, rain, and road wash year-round.

LED units offer faster response times and longer service life compared to incandescent alternatives, and many modern Mercedes-Benz vehicles utilize LED-based CHMSL assemblies as original equipment. A Genuine Mercedes replacement preserves that LED technology and the precise illumination signature the vehicle was designed with, maintaining the cohesive look of the rear lighting cluster.

The Right Choice for Mercedes-Benz Owners

Choosing a Genuine Mercedes Center High Mount Stop Light is the most straightforward path to restoring your vehicle to its original safety specification.
