Honda Motorcycle NCH50 Metropolitan uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2013 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 Honda Motorcycle NCH50 Metropolitan uses the HS1 bulb type for both high beam and low beam headlight positions across the 2013-2016 model years.
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.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage value corresponds to one of the two filaments.
The HS1 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 built to the ECE standard, a regulatory framework recognized across Europe and numerous other markets worldwide.
Because the same HS1 specification applies to both the high beam and low beam positions on the NCH50 Metropolitan, a single bulb type serves the entire headlight assembly.
