The KYMCO MXU 270 headlight bulb uses HS1 size for both high beam and low beam applications. The replacement chart covers 2016 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 270 uses the HS1 bulb type across both its high beam and low beam headlight positions for the 2016-2018 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions within one unit.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments.
The HS1 uses a PX43t base, which is a specific bayonet-style fitting standard to motorcycle and powersports lighting applications and is not interchangeable with automotive bulb bases such as H4.
The HS1 is governed by ECE regulations, a lighting standard recognized across Europe and numerous other markets worldwide.
Because the same HS1 bulb specification applies to both the high beam and low beam positions, the MXU 270 does not use separate single-filament bulbs for each function.
