Honda Motorcycle NCW50 Metropolitan uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2016 to 2020 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 Honda Motorcycle NCW50 Metropolitan uses the HS1 bulb type for both its high beam and low beam headlight positions across the 2016-2020 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both high and low beam functions within one housing.
The HS1 operates at 12 volts with a 35W/35W output rating, where each wattage figure corresponds to one of the two filaments.
The HS1 bulb uses a PX43t base, which is a bayonet-style fitting specific to motorcycle headlight applications and is not interchangeable with common automotive bulb bases such as H4 or H7.
The HS1 is governed by ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, distinguishing it from DOT-regulated bulbs used in North American automotive applications.
Because both the high beam and low beam positions on the NCW50 Metropolitan share the same HS1 specification, a single bulb type serves the entire headlight assembly rather than requiring separate bulbs for each function.
