BMW M6 Headlight Bulb Size

Additional Notes

• The H7 bulb is a halogen type with a single filament, operating at 55 watts on a 12-volt system, and uses a PX26d base. In the BMW M6, H7 serves as the high beam headlight bulb for the 2006-2010 and 2014-2016 model years.
• The D1S bulb is a high-intensity discharge (HID) type that requires a built-in igniter and operates at 35 watts with a starting voltage that can exceed 20,000 volts. It uses an integrated ballast-igniter design, distinguishing it from D2S bulbs, which require a separate igniter.
• In the BMW M6, the D1S bulb appears across both high beam and low beam positions depending on the model year and headlamp configuration. For the 2012-2015 model years, D1S is listed for the high beam only when HID headlamps are fitted, while D1S covers the low beam position across the 2006-2016 model years.
• The 2014-2015 model years of the BMW M6 list both H7 and D1S for the high beam position, indicating that two distinct headlamp systems were available. H7 corresponds to halogen-equipped vehicles, while D1S corresponds to those fitted with HID headlamps. These two bulb types are not interchangeable.
• The 9005 bulb is a halogen type with a single filament rated at 65 watts, using an SB-P20d base. It is listed as the high beam bulb for the 1987-1988 M6 when equipped with halogen capsule headlamps.
• The 9006 bulb is a halogen type rated at 55 watts, using an SB-P22d base, and is not interchangeable with the 9005 despite their physical similarity. It is listed as the low beam bulb for the 1987-1988 M6 with halogen capsule headlamps.
• The H5001 and H5006 are sealed beam units rather than replaceable bulb types. A sealed beam integrates the filament, reflector, and lens into a single non-separable assembly. H5001 covers the high beam and H5006 covers the low beam for the 1987-1988 M6 when fitted with sealed beam headlamps.
• The 1987-1988 M6 carried three distinct headlamp technologies across its high and low beam positions: sealed beam, halogen capsule, and no HID option. This contrasts with later model years, where HID via D1S became the standard low beam solution.
• The D1S bulb is the sole low beam specification for the 2006-2016 model years, with no halogen alternative listed for those years. This indicates that all M6 vehicles produced in that range used HID low beam headlamps regardless of high beam configuration.
• The 2016 model year lists only H7 for the high beam with no D1S high beam option, unlike 2012-2015, which included both. The low beam for 2016 remains D1S, meaning a mixed halogen and HID headlamp system was the sole configuration that year.
