Harley-Davidson FXRS Low Glide headlight bulbs utilize an H5006 size for both high and low beam functions. The replacement chart covers 1982 to 1991 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 FXRS Low Glide uses the H5006 bulb size for both the high beam and low beam headlight positions across all model years from 1982-1991.
The H5006 is an ANSI-standardized sealed beam unit recognized in the United States and Canada, operating at 12 volts.
The H5006 is a 5.75-inch round sealed beam, meaning the lens, reflector, and filament are fused into a single glass unit rather than housing a separate replaceable bulb inside.
Because the H5006 is a sealed beam unit, the entire assembly is replaced when the light fails, not an individual bulb element within it.
The identical H5006 fitment across both beam positions means a single unit type serves the full headlight function on this motorcycle.
The consistent H5006 specification across the entire 1982-1991 production run indicates no headlight assembly changes were made between those model years.
