The KYMCO MXU 300 headlight bulb uses HS1 size for both high and low beam functions. Replacement chart data covers 2010 to 2015 production specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The KYMCO MXU 300 uses the HS1 bulb type for both high beam and low beam headlight positions across the 2010-2015 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb contains separate filaments for both high and low beam functions within one housing.
HS1 bulbs operate on a 12-volt electrical system and carry a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments.
The HS1 uses a PX43t base, a bayonet-style fitting specific to this bulb type, which is not interchangeable with other common automotive or powersports base types such as P43t or BA20d.
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 share the same HS1 specification on this vehicle, a single replacement bulb type serves both functions.
