Additional Notes

The BMW X1 daytime running light specifications cover two bulb types across the listed model years: the H7 for 2021-2022 and the H8 for 2012-2015 when equipped with HID headlamps.
Both the H7 and H8 are single-filament halogen bulbs operating on a 12-volt system, conforming to ECE standards recognized across Europe and worldwide, with approval also extended to the United States.
The H7 bulb uses a PX26d base and draws 55 watts, making it the higher-wattage of the two types present in these specifications.
The H8 bulb uses a PGJ19-1 base and draws 35 watts. The base type differs from the H7, meaning the two bulbs are not interchangeable despite both being single-filament halogen units on a 12-volt system.
The H8 fitment on the BMW X1 (2012-2015) is conditional, applying only to vehicles equipped with HID headlamps. Vehicles without that headlamp configuration fall outside this specification.
The differing base types, PX26d for the H7 and PGJ19-1 for the H8, are a direct physical incompatibility. Substituting one for the other is not supported by the listed specifications.
