BMW X3 2005 Bulb Size
Bulb size chart
This page helps you find the correct bulb sizes for the 2005 BMW X3 by lighting position, so you can match the right bulb to the right socket before you buy. Because trim level, lighting package, market, and body style can change the fitment, it is always smart to verify each location separately instead of assuming every bulb is the same.
For the 2005 BMW X3, the chart covers exterior and interior bulbs such as low beam headlight, fog light, brake light, turn signal, reverse light, license plate light, dome light, and cargo area lighting. Use the bulb position on the vehicle as your guide, since some areas may use different bulb types depending on original equipment and factory options.
Fitment can vary on the 2005 BMW X3, especially between trims, package levels, and different market specifications. Some locations may have halogen bulbs from the factory, while others may already use LED-style replacements or aftermarket conversions. If your X3 has been modified, or if a previous owner changed any bulbs, check the installed bulb before ordering to confirm the base, shape, and connector style. This is especially important for fog lights and front turn signals, where H11 LED, H16 LED, 7506, and 7507 options may appear depending on the setup. Comparing the old bulb to the new one is the safest way to avoid a mismatch.
