The Can-Am Spyder ST uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2013 to 2016.
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 bulb type specified across all headlight positions on the Can-Am Spyder ST for the 2013-2016 model years.
The 9003 is an ANSI-standard dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both high and low beam functions independently.
The 9003 operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange width, and this base type determines physical fitment into the headlight housing.
Because the high beam and low beam positions on the Spyder ST share the same 9003 specification for 2013-2016, a single bulb type serves both functions across the entire headlight assembly.
The 9003 carries an ANSI designation applicable in the United States and Canada, and it is electrically and functionally equivalent to the H4 bulb used under international IEC standards, though base tolerances between the two can differ and may affect fitment.
