BMW Motorcycle R1100R headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 1995 to 2000 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The BMW Motorcycle R1100R uses the 9003 bulb size for both high beam and low beam headlight positions across all model years from 1995-2000.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both high 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, and this base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard used in the United States and Canada, and it is electrically and physically equivalent to the H4 bulb used under European and international standards.
Because the R1100R shares the same 9003 specification across both beam positions for the entire 1995-2000 production span, a single bulb type serves the full headlight assembly without requiring separate part numbers for each function.
The H4/9003 platform is widely produced by multiple manufacturers, which reflects broad aftermarket availability in halogen, heavy-duty, and high-output variants, all sharing the same P43t base and 12V dual-filament configuration.
Substituting a single-filament bulb such as an H1 or H7 into a housing designed for the dual-filament 9003 is not compatible, as the P43t base and internal filament positions differ from single-filament base types.
