Mercedes Turn Signal Switch - Genuine Mercedes 20354500107C45

Product Information

A turn signal switch is a multifunction control mounted on the steering column that allows the driver to activate the vehicle’s turn signals and, in many cases, also operates functions like high beams, hazard lights, or wipers. It sends an electrical signal to the turn signal relay and lights, enabling communication of lane changes or turns to other drivers. A properly functioning switch is vital for both safety and regulatory compliance.

• Turn signals not activating or canceling, even when the lever is engaged.
• Intermittent or inconsistent signal operation, due to worn internal contacts.
• Other functions failing, such as headlights or hazards, if integrated into the switch.

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.
