The KYMCO UXV 450i headlight bulb uses an H8 size for both high beam and low beam applications. The replacement chart covers 2015 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 H8 bulb is a single-filament halogen type operating at 12 volts and 35 watts, fitted with a PGJ19-1 base and built to ECE standards, which govern lighting equipment across Europe and numerous other markets worldwide.
The ECE-rated H8 also carries approval for use in the United States, meaning the same bulb specification is valid across both regulatory environments without substitution.
The KYMCO UXV 450i uses the H8 bulb for both the high beam and low beam headlight positions across the 2015-2018 model years, making a single bulb type sufficient for both functions.
Because the high beam and low beam positions share the same H8 specification, the two circuits rely on separate bulbs rather than a dual-filament unit, which is consistent with the H8 being a single-filament design.
The PGJ19-1 base is specific to the H8 and is not shared with several other common halogen types such as the H11 or H9, which use visually similar but dimensionally distinct bases, making cross-substitution a fitment risk.
