Additional Notes

The H5006 is a 5.75-inch round sealed beam unit operating at 12V. Unlike a conventional replaceable bulb, the entire unit is replaced when the light fails, as the filament, reflector, and lens are fused into a single assembly.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 12V with a 60W high beam filament and a 55W low beam filament. A single 9003 bulb serves both the high beam and low beam functions within one housing.
The Harley-Davidson FXRS-SP Low Rider Sport used the H5006 sealed beam unit for both high beam and low beam headlight positions across the 1986-1991 model years.
The 1993 model year saw a change to the 9003 halogen bulb for both the high beam and low beam headlight positions, replacing the sealed beam format used in prior years.
Both the H5006 and 9003 are ANSI-standard bulbs recognized in the United States and Canada, meaning their specifications conform to a defined North American standardization framework.
The H5006 and 9003 are not interchangeable. The H5006 is a sealed beam unit requiring full assembly replacement, while the 9003 is a replaceable capsule-style halogen bulb seated in a separate reflector housing.
