The KYMCO MXU 150 headlight bulb uses HS1 size for both high beam and low beam applications. 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 150 uses the HS1 bulb type for both 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 unit contains two separate filaments to serve both the high beam and low beam functions within one housing.
The HS1 operates on a 12-volt electrical system and carries 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 bayonet-style mount with a specific pin configuration designed for motorcycle headlight applications. This base type is not interchangeable with common automotive bulb bases such as H4, despite the HS1 and H4 sharing a similar dual-filament halogen design.
The HS1 conforms to ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, governing output, beam pattern, and construction requirements.
Because the high beam and low beam positions both call for the HS1, only one bulb type is needed to service the entire headlight assembly on the MXU 150.
