BMW X1 2021 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for the 2021 BMW X1 by lighting position, so you can match the correct replacement before you buy. Because BMW used different lighting setups depending on trim, package, and market, checking the exact location on the vehicle is the safest way to confirm fitment.
For the 2021 BMW X1, many exterior and interior lights use LED assemblies, while a few positions still use replaceable bulbs. That means some lamps are serviced as complete LED units, while others use common bulb types such as 7507, 7506, 7506R, 64136, 2825, or 98 depending on the specific lamp location.
Fitment can vary with trim, lighting package, body style, and whether the vehicle has halogen or LED headlights, so always compare the bulb position on your X1 with the chart before ordering. This is especially important for tail lights and brake lights, where halogen-headlight cars may use different bulb types than LED-headlight cars, and adaptive lighting can change the brake light bulb specification. If you are converting to aftermarket LED bulbs, check polarity, bulb depth, and heat management, and make sure the bulb will not trigger a warning message or hyperflash. When possible, remove the installed bulb and verify the number printed on the base before purchase, since that is the most reliable way to avoid a mismatch.
