Additional Notes

The H8 bulb is the most frequently listed front fog light size across the BMW M240i specifications, appearing for the 2017, 2019, and 2020 model years, as well as one of two listed sizes for 2018.
The H8 is a single-filament halogen bulb operating at 12V and 35W, built to the ECE standard used in Europe and worldwide, and also approved for use in the United States. It uses a PGJ19-1 base.
The H11 is a single-filament halogen bulb operating at 12V and 55W, also built to the ECE standard and approved in the United States. It uses a PGJ19-2 base.
The 2018 BMW M240i front fog light position lists both H8 and H11 as valid bulb sizes, indicating that more than one fitment existed within that model year.
Although the H8 and H11 are both ECE-standard single-filament halogen bulbs, they are not interchangeable. The H8 uses a PGJ19-1 base while the H11 uses a PGJ19-2 base, and their wattage ratings differ at 35W and 55W respectively.
The difference in wattage between the H8 and H11 is significant in a fog light application, as the H11 draws considerably more power and produces a higher output than the H8.
