BMW X3 2012 Bulb Size
Bulb size chart
This 2012 BMW X3 bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right replacement before you buy. Whether you are changing a headlight, tail light, or small interior lamp, using the correct fitment saves time and avoids returns.
The 2012 BMW X3 can use different bulb types depending on trim, lighting package, and market. This page organizes the available bulb sizes by location to make it easier to identify the right part for your specific X3.
Fitment can vary between halogen and HID-equipped models, and some exterior lamps also differ if the vehicle has adaptive lighting or a specific option package. Aftermarket LED conversions may fit physically but still need the correct base, beam pattern, and electrical compatibility to work properly. Before ordering, check the bulb already installed in your BMW X3 and compare it with the listing for that exact lighting position, especially for fog lights, parking lights, brake lights, and headlights.
