The BMW 760Li uses H7 and D1S bulbs for high beam headlight applications, with D1S and D2S bulbs for low beam headlight functions, representing the specific bulb sizes required for this model. A replacement chart covering 2003 to 2015 model years documents the headlight bulb size specifications across the vehicle's production range.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 is a single-filament halogen bulb rated at 12V and 55W, fitted with a PX26d base. It carries ECE approval for use across Europe and worldwide, with additional approval in the United States and Japan.
The D1S and D2S are both HID (xenon) discharge bulbs rated at 85V and 35W, operating at a significantly higher voltage than the H7 despite drawing less wattage. Both types are designed for projector-type housings and hold ECE standard approval.
A key distinction between the D1S and D2S is the ignition system. The D1S uses a PK32d-2 base and incorporates an integral ignitor within the bulb itself, while the D2S uses a P32d-2 base and requires a separate, externally mounted ignitor. The two types are not interchangeable.
On the BMW 760Li, the high beam position for 2014-2015 accepts either an H7 or a D1S bulb, with the D1S applying specifically to vehicles equipped with HID headlamps. This dual-fitment condition means the correct bulb depends on the headlamp system installed on the individual vehicle.
The low beam position transitioned from the D2S to the D1S between the 2005 and 2006 model years. Because these two bulb types use different bases and ignition configurations, they are not cross-compatible despite sharing the same voltage and wattage ratings.
For the 2003-2008 model years, the high beam position on the BMW 760Li uses the H7 halogen bulb, while the low beam position uses a HID discharge bulb throughout that same span, indicating a mixed headlamp configuration across beam positions.
From 2010 onward, the high beam position shifted to the D1S, aligning it with the low beam position and resulting in a uniform HID fitment across both beam functions for those model years.
