Additional Notes

The H1 bulb, an ECE-standard single-filament halogen type with a P14.5s base rated at 12V and 55W, serves as the high beam bulb in the BMW 750iL for model years 1999-2001 and as the low beam bulb in halogen-equipped units for 1995-1998.
The H7 bulb shares the same 12V, 55W rating as the H1 but uses a PX26d base instead, making the two types physically incompatible despite their identical electrical ratings. It functions as the high beam for 1995-1998 and as the low beam in halogen-equipped 1999-2001 models.
The 9005 bulb follows the ANSI standard used in the US and Canada, carries a P20d base, and operates at 12V, 65W. This higher wattage distinguishes it from the ECE halogen types. It is the high beam bulb for 1988-1994 models.
The 9006 bulb is also an ANSI-standard halogen type, rated at 12V and 55W with a P22d base. Although it shares a wattage rating with the H1 and H7, its base differs from both, and it serves as the low beam bulb across 1988-1994 models.
The D2S is an HID (xenon) discharge bulb operating at 85V and 35W, with a P32d-2 base designed specifically for projector-type housings. Unlike the halogen types, it requires an external ignitor to initiate the arc discharge.
For model years 1993-2001, the BMW 750iL low beam position accommodates two distinct bulb types depending on headlamp configuration, with halogen capsule headlamps and HID headlamps requiring entirely different bulbs. Substituting one type for the other is not supported by the specifications.
A notable transition in high beam bulb standards occurs across the model range. The 1988-1994 models use the ANSI 9005, the 1995-1998 models shift to the ECE H7, and the 1999-2001 models use the ECE H1, reflecting three distinct and non-interchangeable base types across the production span.
The low beam position for 1992 and earlier model years lists only the 9006 with no HID alternative, while 1993 and 1994 models list both the 9006 and D2S, indicating that HID availability in the low beam position began with the 1993 model year.
