BMW X3 2006 Bulb Size
Bulb size chart
This page covers bulb sizes for the 2006 BMW X3 and is organized by lighting position so you can quickly verify the correct fit before ordering. Whether you are replacing a headlight, tail light, license plate lamp, or interior bulb, checking the exact location helps avoid confusion between similar-looking bulbs.
The 2006 BMW X3 uses a mix of standard halogen-style bulbs and LED applications depending on the lamp position and equipment. Because trim and lighting packages can vary, this guide is meant to help you match the bulb to the correct socket on your vehicle, not just the general light type.
For the best fitment results, compare the bulb listed for each position with the bulb already installed in your X3 before buying. Market differences, trim level, and factory lighting packages can change the setup, especially for front fog lights, tail lights, and interior lamps. If you are upgrading from halogen to LED, make sure the replacement is compatible with the housing and electrical system, since some aftermarket LED conversions may need load resistors or may not fit the same way as the original bulb. When in doubt, remove the old bulb and verify the base style and part number before purchase.
