Honda Motorcycle VFR1200F front and rear turn signal bulbs utilize 12496 size, with rear signals also compatible with PY21W bulb size. The replacement chart covers 2010 through 2013 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 12496 is a halogen bulb designated under Philips and Osram part numbering systems, rated at 12 volts and intended for specialty automotive applications.
The PY21W follows the ECE (Economic Commission for Europe) lighting standard, which is recognized across European and international markets. It is a single-filament amber bulb rated at 12 volts and 21 watts, fitted with a BAU15s bayonet base.
The BAU15s base uses an offset pin arrangement that prevents the bulb from being seated in sockets designed for the more common BA15s base, making it physically non-interchangeable with standard single-filament bayonet bulbs.
The Honda Motorcycle VFR1200F uses the 12496 bulb for the front turn signal across the 2010, 2012, and 2013 model years.
The rear turn signal of the VFR1200F uses the 12496 for the 2010 and 2013 model years, while the 2012 model year uses the PY21W instead.
The rear turn signal fitment is not uniform across model years, meaning the 2012 rear socket configuration differs from that of the 2010 and 2013 models and requires a different bulb type.
Both the 12496 and PY21W operate on a 12-volt electrical system, which is standard for motorcycle applications, though their wattage and base types are distinct from one another.
Because the 12496 and PY21W are not interchangeable, substituting one for the other in the rear turn signal position would require verifying socket compatibility for the specific model year in question.
