BMW X4 2018 Bulb Size
Bulb size chart
Looking for bulb sizes for the 2018 BMW X4? This page is designed to help you verify the correct bulb type by lighting position, so you can match the right part to the right lamp before you buy. Because BMW used different lighting setups on the X4, the exact bulb can depend on whether the vehicle has LED headlights, HID headlights, adaptive lighting, or a specific trim and market package.
For the 2018 BMW X4, many exterior lights are listed as LED assemblies, while some positions still use replaceable bulbs such as the rear turn signal, reverse light, and certain brake light applications. Use the bulb chart on this page as a position-by-position reference to avoid confusion between front and rear lamps, or between headlight-related bulbs and body-mounted lights.
Fitment can vary by trim, lighting package, body style, and market, so always compare the bulb position on your vehicle with the chart before ordering. The 2018 X4 may use different headlight setups, including halogen-style replacements, HID systems, or LED-equipped headlights, and those configurations do not always share the same bulb type. If you are considering an aftermarket conversion, make sure the bulb, connector, and housing are compatible, and confirm that the change will not trigger warning messages or beam-pattern issues. The safest approach is to check the bulb currently installed in the vehicle before purchase, especially for items like the glove box, vanity mirror, courtesy, brake, and headlight-related bulbs.
