The Harley-Davidson XR1200 headlight uses a 9003 bulb size for both high beam and low beam functions. The replacement chart covers 2009 to 2012 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 Harley-Davidson XR1200 uses the 9003 bulb across all listed model years, 2009-2012, for both the high beam and low beam headlight positions.
The 9003 is an ANSI-standardized bulb designation recognized in the United States and Canada, operating at 12 volts with a dual-filament halogen construction rated at 60 watts on the high beam filament and 55 watts on the low beam filament.
Because the 9003 contains two filaments within a single housing, it serves both the high and low beam functions from one bulb unit, which is reflected in the XR1200 specifications listing the same part number for both positions.
The 9003 bulb uses a P43t base, a bayonet-style mount with a 43mm cap width, which determines physical socket compatibility and is a critical factor in fitment.
The 9003 designation is the ANSI equivalent of the internationally designated H4 bulb. While the two types share the same filament configuration and base style, they are not always interchangeable due to differences in the lens optics each standard is designed to work with.
