BMW Motorcycle R1150RS high beam and low beam headlight bulbs both use a 9003 size. The replacement chart covers 2001 to 2004 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 9003 bulb is the sole bulb type specified across all headlight positions on the BMW Motorcycle R1150RS for the 2001-2004 model years.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it a regionally defined specification rather than a universal one.
As a dual-filament halogen bulb, the 9003 houses two separate filaments within a single envelope, which allows it to serve both the high beam and low beam functions from one unit.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The R1150RS uses the same 9003 bulb for both the high beam and low beam headlight positions, meaning a single bulb type covers both lighting functions on the motorcycle.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. A bulb with a different base type would not be physically compatible with this socket, regardless of voltage or wattage ratings.
The 9003 and HB2 designations refer to the same bulb under different naming conventions. The 9003 follows the ANSI system while HB2 follows the ECE system, though both describe an identical component.
