The Yamaha XVS1300 V Star 1300 uses a P21/5W bulb size for front turn signals and 12496 or PY21W bulb sizes for rear turn signals. The replacement chart covers 2014 through 2017 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 P21/5W is a dual-filament bulb operating at 12V with a 21W main filament and a 5W secondary filament. It uses a BAY15d bayonet base, which is an offset twin-pin fitting designed to prevent incorrect installation.
The Yamaha XVS1300 V Star 1300 uses the P21/5W bulb across all front turn signal positions for the 2014-2017 model years.
The PY21W is a single-filament amber bulb rated at 12V and 21W. It uses a BAU15s bayonet base, which has asymmetrically offset pins. This base differs from the BAY15d used by the P21/5W, making the two bulbs physically non-interchangeable despite their similar wattage ratings.
The 12496 is a part number used by manufacturers such as Philips and Osram to designate a specialty halogen bulb rated at 12V. It appears in the rear turn signal position for the 2015 and 2017 model years.
The rear turn signal specification alternates between two different bulb types across the 2014-2017 model years. The 2014 and 2016 models specify the PY21W, while the 2015 and 2017 models specify the 12496.
Both the P21/5W and PY21W conform to ECE standards, indicating they are approved for road use in Europe and other markets that follow ECE lighting regulations.
The BAU15s base of the PY21W and the BAY15d base of the P21/5W are physically distinct. Substituting one for the other is not possible without modification, as the pin offset geometry differs between the two base types.
The front and rear turn signal positions on the XVS1300 V Star 1300 do not share a common bulb type for any of the 2014-2017 model years, as the front uses the P21/5W while the rear alternates between the PY21W and 12496.
