Harley-Davidson FXWG Wide Glide headlight bulbs utilize an H5006 size for both high and low beam functions. The replacement chart covers 1980 to 1984 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 H5006 is an ANSI-standardized sealed beam unit operating at 12 volts, used across all listed model years of the Harley-Davidson FXWG Wide Glide for both high beam and low beam headlight positions.
A sealed beam unit integrates the filament, reflector, and lens into a single non-serviceable assembly, meaning the entire unit requires replacement rather than an individual bulb.
The H5006 measures 5.75 inches in round format, a sizing standard that was common in motorcycle and automotive lighting applications governed by ANSI specifications applicable in both the United States and Canada.
The Harley-Davidson FXWG Wide Glide uses the same H5006 specification for both the high beam and low beam functions across the 1980-1984 model years, indicating a single sealed beam unit serves dual-beam purposes.
Because the H5006 is an ANSI-standardized type, units produced by different manufacturers to the same standard are generally interchangeable, provided they conform to the 5.75-inch round sealed beam specification at 12 volts.
Substituting a non-sealed-beam retrofit or an incompatible sealed beam of a different size or voltage rating would fall outside the fitment specification for this application.
