Honda Motorcycle NSS300A Forza ABS Headlight Bulb Size
Honda Motorcycle NSS300A Forza ABS uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2014 to 2016 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 HS1 bulb is the sole bulb type specified across all headlight positions for the Honda Motorcycle NSS300A Forza ABS, covering both high beam and low beam functions for the 2014-2016 model years.
The HS1 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments to serve both high and low beam functions within one housing.
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 wattage in this specification.
The HS1 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, indicating it is designed for markets operating under European and international lighting regulations rather than SAE (North American) standards.
Because the high beam and low beam positions share the same HS1 specification for the NSS300A Forza ABS (2014-2016), the same bulb part number applies to both sockets, though the sockets themselves remain separate installations.
