BMW Torx Screw Micro-Encapsulated (M5X128 8 Zns3) - Genuine BMW 23147576178

Product Information

The back-up light switch is an electrical component that activates the reverse lights when the transmission is shifted into reverse gear. Mounted on the transmission or gear selector mechanism, it signals the vehicle’s lighting system to illuminate the rear back-up lamps, improving visibility and alerting others that the vehicle is reversing. Built with durable contacts and housings to withstand heat, vibration, and fluid exposure, the switch is essential for both safety and compliance with vehicle regulations.

• Reverse lights do not illuminate – often due to a failed or worn-out switch.
• Intermittent or flickering reverse lights – caused by loose connections or failing internal contacts.
• Check engine light or transmission-related fault codes – may appear if the switch malfunctions on electronically controlled systems.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

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