BMW X2 high beam and low beam headlight bulbs both use H7 size. The replacement chart covers 2018 to 2020 vehicle production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 bulb is the sole bulb type specified across all listed years and positions for the BMW X2, covering both high beam and low beam headlight functions.
The H7 is a single-filament halogen bulb operating at 55 watts with a PX26d base, a two-pin bayonet-style connector that is not interchangeable with other common base types such as P43t or PGJ19.
For the 2019-2020 model years, the H7 fitment is explicitly conditioned on the presence of Halogen Capsule Headlamps, indicating that alternative headlamp configurations exist on those vehicles and do not share this bulb specification.
The 2018 model year carries no such conditional note for either beam position, meaning the H7 fitment applies without a stated headlamp-type qualifier for that year.
Because the high beam and low beam positions share the same H7 bulb type across all listed years, the vehicle uses a projector or reflector housing design with separate bulb units for each function rather than a dual-filament arrangement.
H7 bulbs are not interchangeable with the physically similar H1 or H4 types; the PX26d base is specific to H7 and prevents cross-fitting without an adapter, which is generally not recommended for safety-critical lighting.
Owners of 2019-2020 X2 vehicles with non-halogen headlamp systems, such as LED or adaptive units, would reference a different bulb specification entirely, as the H7 entries do not apply to those configurations.
