BMW X3 2020 Bulb Size
Bulb size chart
This 2020 BMW X3 bulb size guide helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Because trim level, lighting package, and market can change the exact fitment, it is best to confirm the bulb type for each lamp on your vehicle.
Use the chart on this page to check common exterior and interior bulb locations on the 2020 BMW X3, including headlights, fog lights, brake lights, turn signals, parking lights, reverse lights, and vanity mirror lights. Looking up bulbs by position is the easiest way to avoid ordering the wrong replacement.
Fitment can vary between trims and lighting packages, especially on vehicles with adaptive lighting or factory LED equipment. A halogen setup may use different bulbs than an LED or adaptive version, and aftermarket conversions can change what is actually installed.
