The KYMCO MXU 375 headlight bulb uses HS1 and H8 sizes for both high beam and low beam applications. The replacement chart covers 2010 through 2013 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 HS1 bulb is a dual-filament halogen type rated at 12V with a 35W/35W output, meaning it carries separate filaments for two distinct lighting functions within a single housing. It uses a PX43t base and conforms to ECE standards recognized across Europe and worldwide.
The H8 bulb is a single-filament halogen type rated at 12V, 35W, fitted with a PGJ19-1 base. Unlike the HS1, it carries ECE approval alongside US market approval, broadening its regulatory acceptance.
The HS1 and H8 are not interchangeable. Their base types differ, with the PX43t base of the HS1 and the PGJ19-1 base of the H8 being physically incompatible with each other's sockets.
On the KYMCO MXU 375, the high beam and low beam headlight positions share the same bulb size for each model year, meaning a single bulb type serves both functions in a given year.
The 2011 and 2013 model years specify the HS1 for both headlight positions, while the 2010 and 2012 model years specify the H8 for both positions.
The alternating bulb specifications across model years indicate that the 2010-2013 production run of the MXU 375 did not use a consistent headlight bulb type throughout, requiring year-specific verification before replacement.
