BMW Motorcycle R1200C headlight bulb uses a 9003 size for both high and low beam applications. The replacement chart covers 1996 to 2005 model 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 R1200C uses the 9003 bulb for both high beam and low beam headlights across all model years from 1996-2005.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. A replacement bulb must carry this same base type to seat correctly in the R1200C headlight housing.
The 9003 is an ANSI-designated standard applicable in the United States and Canada. It is electrically and physically equivalent to the European H4 bulb, though the two designations originate from different regional standards bodies.
Because the 9003 and H4 share the same base and filament configuration, aftermarket and OEM replacements sold under either designation are generally interchangeable in the BMW Motorcycle R1200C headlight socket.
