The KYMCO MXU 500 headlight bulb uses HS1 size for both high beam and low beam functions. The replacement chart covers 2010 to 2018 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 KYMCO MXU 500 uses the HS1 bulb type for both its high beam and low beam headlight positions across the 2010-2018 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments that serve both the high beam and low beam functions within one unit.
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 mount with a specific pin configuration designed for motorcycle headlight housings.
The HS1 is built to the ECE standard, a regulatory framework recognized across Europe and numerous other markets worldwide.
Because both the high beam and low beam positions share the same HS1 specification on the MXU 500, a single bulb type covers both headlight functions on this vehicle.
The HS1 bulb type is specific to motorcycle and powersports applications and is not interchangeable with the H4 bulb, which shares a similar dual-filament design but uses a different base configuration incompatible with PX43t sockets.
