Mercedes Mirror Turn Signal Assembly - Genuine Mercedes 171820042164

Product Information

A turn signal light, also known as an indicator or blinker, is a critical part of a vehicle’s safety system that signals your intent to turn or change lanes. The lights are located at the front, rear, and sometimes on the sides of the vehicle, and they flash on and off when the driver activates the turn signal lever. The turn signals inform other drivers, cyclists, and pedestrians of the vehicle’s movements to help prevent accidents.

• Turn Signal Light Not Blinking: The most obvious sign of failure is when the turn signal doesn't blink or activate at all. This can be caused by a blown bulb, faulty wiring, or a bad turn signal switch.
• Rapid Flashing: If the turn signal blinks much faster than normal, this often indicates a burned-out bulb.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz.

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.
