MINI Taillight/Turn Signal Bulb Socket (P21W) - Genuine MINI 63212756177

Product Information

A turn signal light socket is the electrical connector that holds and powers the turn signal bulb within the vehicle’s lighting assembly. It ensures a secure fit for the bulb and provides the necessary electrical contact to activate the signal when engaged. A properly functioning socket is essential for reliable turn signal operation, which is critical for vehicle safety and communication with other drivers.

• Intermittent or non-functioning turn signal, often caused by poor electrical contact.
• Burnt or melted socket housing, due to overheating or electrical resistance.
• Corrosion or moisture buildup, leading to dim or flickering bulb operation.

About Genuine Mini

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

You may not realize this, but the parts that make up your Mini are not necessarily manufactured by Mini. No cause for concern, as Mini designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mini 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 Mini parts box and find an OEM branded part inside, simply with the addition of a Mini logo.
