BMW Motorcycle K1200RS high beam headlight uses an H3 bulb size while the low beam headlight requires an H7 bulb size. The replacement chart covers 1997 to 2005 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW Motorcycle K1200RS uses the H3 bulb for high beam and the H7 bulb for low beam across all model years from 1997-2005.
Both the H3 and H7 are single-filament halogen bulbs operating at 12 volts and 55 watts, meaning each bulb handles only one lighting function rather than combining high and low beam in a single unit.
The H3 uses a PK22s base, while the H7 uses a PX26d base. These two base types are physically incompatible with each other, so the bulbs are not interchangeable between the high beam and low beam positions.
Both bulbs conform to ECE standards, which are recognized in Europe, the US, and Japan, reflecting broad international regulatory acceptance for road use.
The consistent use of H3 for high beam and H7 for low beam across all nine model years from 1997-2005 indicates no variation in bulb fitment requirements throughout the entire production span covered by these specifications.
