BMW X3 2014 Bulb Size
Bulb size chart
The 2014 BMW X3 uses different bulb sizes depending on the lighting position, so this page is designed to help you verify the correct bulb by location before you buy. Whether you are replacing a headlight, brake light, reverse light, or a small exterior marker lamp, matching the bulb to the exact spot on the vehicle is the safest way to avoid fitment problems.
Because BMW offered the X3 with different trim levels and lighting packages, the bulb list can vary by market and body style. This 2014 BMW X3 bulb guide brings the common exterior lighting positions together in one place, making it easier to identify the right bulb type for your specific setup.
For best results, compare your vehicle’s current bulb before ordering, especially if your X3 has halogen headlights, HID headlights, or an optional lighting package. Some positions use LED assemblies, while others still rely on replaceable bulbs, and aftermarket LED conversions may fit differently than the original halogen or HID design. If you are unsure, check the installed bulb number, inspect the socket shape, and confirm the lighting option on your vehicle before purchase.
