The BMW ActiveHybrid 5 high beam and low beam headlight bulbs both utilize the D1S bulb size. The replacement chart contains vehicle production years and bulb size specifications spanning 2012 to 2016.
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 sole bulb type specified across all model years and both high beam and low beam positions for the BMW ActiveHybrid 5.
D1S is a High-Intensity Discharge (HID) xenon bulb rated at 85 volts and 35 watts, operating at significantly higher voltage than conventional halogen bulbs, which typically run at 12 volts.
The D1S bulb features a PK32d-2 base with an integral ignitor built directly into the bulb body, meaning the ignitor is not a separate component and is replaced along with the bulb itself.
D1S bulbs are designed exclusively for projector-type headlamp housings and are not interchangeable with reflector-type housings, which use different bulb families such as D2S or D2R.
The D1S standard follows ECE regulations, which govern bulb performance and safety requirements across Europe and many other markets worldwide.
For the 2014-2016 BMW ActiveHybrid 5, the D1S fitment is explicitly noted as applying to vehicles equipped with HID headlamps, indicating that the headlamp system type is a relevant fitment condition for those years.
Both the high beam and low beam positions share the same D1S bulb type across all listed years (2012-2016), which is a characteristic of projector-lens HID systems that use a single bulb with a mechanical shield to switch between beam patterns.
