Additional Notes

The 9003 is a dual-filament halogen bulb, meaning a single unit contains both the high beam and low beam filaments. This design explains why the same bulb size appears under both the High Beam and Low Beam Headlight categories for the 1987-1993 model years of the Harley-Davidson FLHS Electra Glide Sport.
The 9003 operates at 12 volts and draws 60 watts on high beam and 55 watts on low beam. It uses a P43t base, which is a bayonet-style mount with a 43mm collar.
The H5006 is a sealed beam unit rather than a replaceable bulb. When the light fails, the entire assembly is replaced as one piece, as the lens, reflector, and filament are fused together inside a single glass housing.
The H5006 is specified as a 5.75-inch round sealed beam and operates at 12 volts. It follows the ANSI standard applicable to the United States and Canada.
The FLHS Electra Glide Sport used the H5006 sealed beam unit across the 1980-1984 model years, while the 9003 halogen bulb was fitted from 1987-1993. These two bulb types are not interchangeable with each other due to fundamentally different construction and mounting formats.
The 9003 also carries the designation HB2 under international standards and is physically identical to the H4 bulb used in many markets outside North America. However, the 9003 designation reflects the ANSI standard specific to the US and Canada.
