The KYMCO Maxxer 375 headlight bulb size specifications include H8 and HS1 bulb options for both high beam and low beam applications. The replacement chart covers 2010 to 2011 production years with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The KYMCO Maxxer 375 uses two distinct bulb types across its model years: the H8 in 2011 and the HS1 in 2010, with both the high beam and low beam positions sharing the same bulb type within each respective year.
The H8 is a single-filament halogen bulb operating at 12V and 35W, fitted with a PGJ19-1 base and rated to the ECE standard, which covers Europe and worldwide markets, with additional approval for use in the United States.
The HS1 is a dual-filament halogen bulb designed for motorcycle applications, operating at 12V with 35W on each filament, fitted with a PX43t base, and also rated to the ECE standard.
Because the H8 carries a single filament and the HS1 carries two, the two bulb types are not interchangeable despite sharing the same wattage rating on their respective filaments.
The base types differ between the two bulbs, with the PGJ19-1 base on the H8 and the PX43t base on the HS1, meaning the physical socket configuration changed between the 2010 and 2011 model years.
Since both the high beam and low beam positions use the same bulb specification in each model year, the 2010 Maxxer 375 relies on the dual-filament HS1 to serve both functions, a configuration typical of motorcycle lighting systems where a single bulb housing handles both beam modes.
