The BMW 228i uses D1S and H15 bulbs for high beam headlights, while low beam headlights require D1S and H7 bulbs in their respective sizes. The replacement chart covers 2014 to 2016 model years with corresponding bulb size specifications for each headlight function.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW 228i (2014-2016) uses two distinct headlamp systems: HID (High Intensity Discharge) and halogen capsule. The correct bulb type depends entirely on which system is installed in the vehicle, and the two systems are not interchangeable.
The D1S is an HID xenon discharge bulb operating at 85V and 35W. Unlike halogen bulbs, it incorporates an integral ignitor within the bulb assembly and is designed exclusively for projector-type housings. It uses a PK32d-2 base.
The H15 is a dual-filament halogen bulb rated at 12V with a 55W main filament and a 15W secondary filament. It uses a PGJ23t-1 base and serves the high beam function on 228i vehicles equipped with halogen capsule headlamps.
The H7 is a single-filament halogen bulb rated at 12V and 55W, fitted with a PX26d base. It handles the low beam function on halogen-equipped 228i vehicles across the 2014-2016 model years.
All three bulb types, D1S, H15, and H7, conform to ECE standards, meaning they are rated for use in Europe and worldwide markets. The H7 additionally carries approval for use in the United States and Japan.
On HID-equipped 228i vehicles, the D1S serves both the high beam and low beam positions. This dual-position application is a characteristic of certain projector-type housing designs where a single bulb type manages both functions.
The base types across the three bulbs are entirely distinct: PK32d-2 for the D1S, PGJ23t-1 for the H15, and PX26d for the H7. These differing bases physically prevent cross-installation between bulb types.
The halogen capsule configuration of the BMW 228i uses two different bulb types within the same headlamp assembly: the H15 for high beam and the H7 for low beam, each occupying a separate socket.
