BMW Motorcycle R1200RS headlight bulbs utilize H7 size specifications for both high beam and low beam functions. The replacement chart covers 2015 to 2018 model years with corresponding bulb size data.
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 operating at 12 volts and 55 watts, fitted with a PX26d base, which is a two-pin bayonet-style connector that locks into a specific orientation to ensure correct filament positioning.
The H7 designation follows the ECE (Economic Commission for Europe) standard, giving it regulatory approval across Europe, worldwide markets, the United States, and Japan.
The BMW Motorcycle R1200RS uses the H7 bulb size for both the high beam and low beam headlight positions across the 2015-2018 model years.
Because both the high beam and low beam positions share the same H7 specification, the two housings accept physically identical bulbs, though each position remains a separate, dedicated unit rather than a shared dual-function assembly.
The single-filament construction of the H7 means each bulb serves only one lighting function, which is why separate bulbs are required for the high and low beam positions rather than a single dual-filament unit.
The PX26d base is not interchangeable with other common halogen bases such as the H4's P43t or the H11's PGJ19-2, meaning bulbs of those types are not compatible with R1200RS headlight housings regardless of voltage or wattage.
