Mercedes Third Stop Light - Genuine Mercedes 209820105664

Product Information

A Center High Mount Stop Light, also known as the third brake light, is the red warning light mounted higher than the vehicle’s left and right brake lights — usually at the top of the rear window, trunk lid, or roofline. It provides an extra level of visibility to alert drivers behind when the brakes are applied.

• Light does not illuminate when braking – could be due to a burned-out bulb (halogen), bad LED module, faulty wiring, or blown fuse.
• Dim or flickering light – often from poor electrical contact, corroded connectors, or weakening LEDs.
• Partial illumination (for LED strips) – some sections work while others fail, showing an uneven light pattern.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
