Honda Motorcycle PS250 Big Ruckus Headlight Bulb Size
Honda Motorcycle PS250 Big Ruckus headlight bulbs utilize a 9003 size for both high beam and low beam functions. The replacement chart covers 2005 to 2006 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 9003 is an ANSI-standard dual-filament halogen bulb rated at 12 volts, with a high beam filament drawing 60 watts and a low beam filament drawing 55 watts. It uses a P43t base, which is a bayonet-style fitting common in North American automotive and motorcycle lighting applications.
Because the 9003 carries both filaments within a single bulb, it serves both the high beam and low beam functions in the Honda PS250 Big Ruckus across the 2005-2006 model years, rather than requiring separate bulbs for each function.
The 9003 designation is the ANSI standard used in the United States and Canada. It is electrically and physically equivalent to the international HB2 designation, meaning bulbs sold under either designation are interchangeable in practice.
The P43t base is a standardized fitting, and the 9003 shares this base with the H4 bulb type. However, the 9003 and H4 differ in their filament positioning and light output characteristics, so substitution between the two is not straightforward despite the shared base type.
