Harley-Davidson FXLR Low Rider Custom headlight bulbs utilize 9003 and H5006 sizes for both high and low beam functions. The replacement chart covers 1991 through 1994 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 9003 bulb is a dual-filament halogen type rated at 12V with a 60W high beam filament and a 55W low beam filament, fitted with a P43t base. Its dual-filament design allows a single bulb to serve both the high beam and low beam functions within one housing.
The H5006 is a 5.75-inch round sealed beam unit operating at 12V. Unlike a conventional replaceable bulb, the lens, reflector, and filament are fused into a single assembly, meaning the entire unit requires replacement when the filament fails.
On the Harley-Davidson FXLR Low Rider Custom, the 1993-1994 model years use the 9003 bulb for both the high beam and low beam headlight positions.
The 1991 model year uses the H5006 sealed beam unit for both the high beam and low beam headlight positions, representing a fundamentally different construction from the 9003 used in later years.
Because the 9003 and H5006 are structurally incompatible, the 1991 fitment is not interchangeable with the 1993-1994 fitment. The sealed beam format of the H5006 and the socketed halogen format of the 9003 require different headlight housings.
Both the 9003 and H5006 carry ANSI standard designations applicable to the United States and Canada, indicating conformance to a defined set of photometric and dimensional standards within those markets.
