The BMW ActiveHybrid 7 high beam and low beam headlight bulbs both utilize the D1S bulb size. The replacement chart covers vehicle production spanning 2013 to 2015.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW ActiveHybrid 7 uses the D1S bulb for both high beam and low beam headlights across the 2013-2015 model years, with all configurations requiring HID headlamps.
The D1S is a High-Intensity Discharge (HID) xenon bulb operating at 85 volts and 35 watts, placing it in the low-wattage, high-output category typical of automotive discharge lighting.
A defining characteristic of the D1S is its integral ignitor, which is built directly into the bulb unit rather than housed separately in the vehicle's electrical system.
The D1S uses a PK32d-2 base, a keyed connector design that physically prevents installation of incompatible bulb types in the same socket.
D1S bulbs are engineered specifically for projector-type headlamp housings, meaning they are not interchangeable with reflector-type housings without modification to the housing itself.
The D1S carries ECE certification, a regulatory standard recognized across Europe and numerous other markets worldwide, governing light output, color temperature, and safety compliance.
Because the high beam and low beam positions share the same D1S specification on the BMW ActiveHybrid 7, the vehicle relies on the projector housing mechanism rather than separate bulb types to switch between beam modes.
