The KYMCO Xciting 500 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production spanning 2010 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 bulb is the sole headlight bulb type specified for the KYMCO Xciting 500 across all listed model years, appearing in both the high beam and low beam positions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam output and one rated at 55W for low beam output.
The bulb operates on a 12V electrical system and uses a P43t base, which is a bayonet-style fitting with a 43mm collar width.
The 9003 designation follows the ANSI standard used in the United States and Canada. It is electrically and functionally equivalent to the H4 bulb used under European ECE standards, though physical base differences between some 9003 and H4 variants can affect interchangeability depending on the socket design.
Because both the high beam and low beam positions on the Xciting 500 share the same 9003 specification, a single bulb type serves the entire headlight assembly rather than requiring separate bulbs for each function.
The specifications cover model years 2010-2014 and 2016-2017, with the 9003 fitment remaining consistent throughout all of those years.
