Harley-Davidson FXRS-Conv Low Rider Sport Convertible Headlight Bulb Size
Harley-Davidson FXRS-Conv Low Rider Sport Convertible headlight bulbs utilize a 9003 or H5006 size for both high and low beam functions. The replacement chart covers 1990 to 1993 model 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 is a dual-filament halogen bulb, meaning a single bulb contains both the high beam and low beam filaments. This explains why the 1993 Harley-Davidson FXRS-Conv Low Rider Sport Convertible lists the same 9003 bulb for both the high beam and low beam positions.
The 9003 operates at 12V and draws 60W on high beam and 55W on low beam. It uses a P43t base, which is a standardized bayonet-style fitting common to many halogen headlight applications.
The H5006 is a 5.75-inch round sealed beam unit. Unlike a conventional replaceable bulb, the lens, reflector, and filament are fused into a single glass assembly, so the entire unit is replaced when the light fails.
The H5006 is rated at 12V with no separate wattage split between beam modes, consistent with sealed beam units of its type, which typically house a single fixed filament configuration.
Both the 9003 and H5006 are ANSI-standard bulbs certified for use in the United States and Canada, indicating they conform to defined photometric and dimensional standards for those markets.
The 1990 model uses the H5006 sealed beam unit, while the 1993 model uses the 9003 halogen bulb. These two bulb types are not interchangeable, as they differ in construction, base type, and installation method.
