Honda Motorcycle SA50 Elite headlight bulbs utilize HS1 size for both high and low beam functions. The replacement chart covers 1988 to 2001 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Motorcycle SA50 Elite uses the HS1 bulb type for both its high beam and low beam headlight positions across all specified model years from 1988-2001.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both the high beam and low beam functions rather than requiring two distinct bulbs.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments, both drawing equal power.
The HS1 bulb uses a PX43t base, a bayonet-style fitting specific to motorcycle headlight applications, which is not interchangeable with common automotive bulb bases such as H4 despite the H4 also being a dual-filament halogen type.
The HS1 is governed by ECE (Economic Commission for Europe) standards, a regulatory framework recognized across Europe and numerous other markets worldwide, distinguishing it from bulbs designed solely to SAE (North American) standards.
Because both the high beam and low beam positions share the same HS1 specification throughout the 1988-2001 range, a single bulb type serves the entire headlight assembly of the SA50 Elite.
