The KYMCO UXV 500i headlight bulb uses HS1 size for both high beam and low beam applications. The replacement chart covers vehicle production years from 2010 to 2018 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 for the KYMCO UXV 500i across all listed model years, covering both the high beam and low beam headlight positions for the 2010-2018 range.
The HS1 is a dual-filament halogen bulb, meaning a single bulb unit contains separate filaments for both high and low beam functions, operating at 12 volts with a 35W rating on each filament.
The HS1 bulb uses a PX43t base, which is a bayonet-style fitting specific to this bulb type. This base is not interchangeable with other common automotive or powersports bulb bases such as H4 or H7, despite the HS1 serving a functionally similar dual-filament role.
The HS1 standard falls under ECE regulation, which is the framework used in Europe and numerous other markets worldwide. This origin distinguishes it from SAE-governed bulb types more commonly associated with North American automotive applications.
Because both the high beam and low beam positions share the same HS1 specification across all listed years, a single replacement bulb type serves both functions on the UXV 500i.
