The Can-Am Spyder F3 front turn signal uses a PY21W bulb size, while the rear turn signal requires a P21/5W bulb size. The replacement chart covers 2015 to 2019 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Can-Am Spyder F3 front turn signal uses two distinct bulb types across its model years: the 12496 for 2015-2017 and the PY21W for 2018.
The PY21W is an ECE-standard single-filament amber bulb rated at 12V and 21W, fitted with a BAU15s bayonet base.
The BAU15s base features an offset pin arrangement, which physically prevents substitution with standard BAY15d or BA15s base bulbs.
The 12496 is a Philips/Osram part number designation for a 12V halogen bulb intended for specialty applications.
The rear turn signal across all listed years, 2015-2019, uses the P21/5W bulb exclusively on the Can-Am Spyder F3.
The P21/5W is an ECE-standard dual-filament bulb rated at 12V with a 21W primary filament and a 5W secondary filament, mounted on a BAY15d bayonet base.
The BAY15d base uses two pins at different heights to ensure correct filament orientation, making it non-interchangeable with single-filament BAY15s or offset BAU15s bases.
The front turn signal bulb type changed between the 2017 and 2018 model years, shifting from the 12496 to the PY21W, which represents a change in both the part number system and the base type.
