The Yamaha XVS650 V Star uses a 1034NA bulb size for front turn signals and a PY21W bulb size for rear turn signals. The replacement chart covers 2014 through 2016 model 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 Yamaha XVS650 V Star uses two distinct turn signal bulb types across its front and rear positions for the 2014-2016 model years, with each position requiring a specific bulb that is not interchangeable with the other.
The front turn signal on the 2014-2016 XVS650 V Star takes the 1034NA bulb, an ANSI-standard type used in the United States and Canada.
The 1034NA is a dual-filament bulb rated at 12V and 21/5W, meaning it carries separate wattage outputs for its two filaments, typically serving both a brighter signaling function and a dimmer running or parking function.
The 1034NA uses a BAY15d bayonet base, which features two offset pins at different heights to ensure correct filament orientation during installation.
The 1034NA is a variant of the widely used 1157 bulb and features natural amber glass, which produces the amber signal color directly from the bulb rather than relying on a colored lens.
The rear turn signal on the 2014-2016 XVS650 V Star takes the PY21W bulb, an ECE-standard type used in Europe and worldwide markets.
The PY21W is a single-filament bulb rated at 12V and 21W, serving only one function per bulb rather than the dual roles of the front 1034NA.
The PY21W uses a BAU15s bayonet base, which has two pins at the same height but offset angularly, a design that prevents accidental substitution with other 15mm bayonet bulbs that use differently keyed bases.
Because the BAY15d base of the 1034NA and the BAU15s base of the PY21W are physically incompatible, the front and rear turn signal bulbs on the XVS650 V Star cannot be substituted for one another.
The presence of an ANSI-standard bulb at the front and an ECE-standard bulb at the rear reflects a mixed-standard fitment, where the two positions draw from different international specification systems despite belonging to the same vehicle.
