BMW Side Marker Light Bulb - Genuine BMW 63217160798

Product Information

A side marker light is a small, sometimes amber, or clear reflector light mounted on the sides of a vehicle, typically near the front or rear corners. Its primary purpose is to make the vehicle more visible from the side, especially during low-light conditions or at night, improving overall road safety.

• Cracked or Damaged Lens: Physical damage to the side marker light's lens can allow moisture or dirt to enter, leading to bulb failure or corrosion in the wiring. If the lens is cracked or broken, it should be replaced to prevent further damage.
• Corrosion or Water Damage: If the light housing is not properly sealed or has been damaged, water can get inside, causing corrosion to the electrical contacts and wires. This can result in a malfunctioning light, and you might see moisture buildup inside the lens.

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.
