BMW X6 high beam headlight bulbs use D1S and H7 sizes, while low beam headlight bulbs use D1S bulb size. The replacement chart contains vehicle production years and bulb size specifications spanning 2008 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The D1S bulb is the most frequently specified type across the BMW X6 headlight data, appearing in both high beam and low beam positions for every model year listed from 2008 through 2019. It is a high-intensity discharge xenon bulb rated at 85V and 35W, fitted with a PK32d-2 base and a built-in ignitor, and is designed specifically for projector-type headlight housings.
The H7 is a single-filament halogen bulb rated at 12V and 55W, using a PX26d base. It carries ECE approval for European and worldwide markets and is also approved for use in the United States and Japan.
For the BMW X6, the H7 bulb appears exclusively in the high beam position and only for model years 2009-2016, where it serves as an alternative fitment alongside the D1S on vehicles not equipped with HID headlamps.
The low beam position across all listed model years from 2008 through 2019 is served solely by the D1S bulb, with no halogen alternative specified for that position at any year.
From 2013 through 2019, the high beam D1S entries carry an explicit "With HID Headlamps" qualifier, indicating that this bulb applies only to vehicles fitted with HID headlamp assemblies rather than to all configurations.
The D1S and H7 bulbs use physically incompatible bases, PK32d-2 and PX26d respectively, meaning the two types are not interchangeable with each other regardless of wattage or application.
The integral ignitor built into the D1S bulb is a distinguishing characteristic of the D1S design. Because the ignitor is part of the bulb itself rather than a separate component in the housing, replacement of the bulb also replaces the ignitor.
The 2008 model year high beam position lists only the D1S with no H7 alternative, while the low beam for that same year also specifies the D1S, making 2008 the only listed year where both positions carry a single bulb type with no conditional fitment noted.
