BMW Motorcycle R1150R headlight bulbs utilize a 9003 size for both high and low beam functions. The replacement chart covers 2001 to 2006 model 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 R1150R uses the 9003 bulb type across all listed model years (2001-2006) for both high beam and low beam headlight positions.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of what is internationally classified as the H4 bulb.
As a dual-filament halogen bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, with one filament dedicated to high beam output and the other to low beam output.
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 P43t base is a bayonet-style mount with three positioning lugs arranged asymmetrically, a design that ensures the bulb can only be seated in one correct orientation to align the filaments with the reflector optics.
Because the R1150R uses a single 9003 bulb to serve both beam functions simultaneously, the high beam and low beam positions share the same socket and the same physical bulb rather than separate units.
The P43t base of the 9003 is not interchangeable with single-filament halogen bases such as the H1 or H7, which use different base configurations and wattage ratings.
