The Yamaha XVS13 Stryker uses a 1034NA bulb size for front turn signals and PY21W or 12496 bulb sizes for rear turn signals. The replacement chart covers 2011 through 2014 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 Yamaha XVS13 Stryker uses two distinct bulb standards across its front and rear turn signal positions, reflecting different regional and functional requirements for each location.
The 1034NA is the front turn signal bulb for the XVS13 Stryker across the 2011-2014 model years. It is a dual-filament bulb rated at 12V and 21/5W, built to ANSI standards for the US and Canadian markets.
The 1034NA uses a BAY15d bayonet base and features natural amber glass. It is a variant of the widely available 1157 bulb, though the amber glass coating distinguishes it from the clear-lensed 1157.
The rear turn signal position on the 2012-2014 XVS13 Stryker uses the PY21W bulb. This is a single-filament amber bulb rated at 12V and 21W, built to ECE standards used in European and international markets.
The PY21W uses a BAU15s bayonet base, which is offset at a different angle than the BAY15d base found on the 1034NA. These two bases are not interchangeable, and substituting one bulb for the other is not physically possible without modification.
The single-filament design of the PY21W means it serves only one signaling function, unlike the dual-filament 1034NA, which handles two separate circuit functions through its two filaments.
The 2011 XVS13 Stryker rear turn signal uses the 12496, a Philips/Osram part number designating a 12V halogen bulb intended for specialty applications. This differs from the PY21W used in the 2012-2014 rear position.
Because the 2011 rear turn signal specifies the 12496 by a manufacturer part number rather than a universal standard, direct substitution with generic equivalents warrants verification of base type and wattage compatibility.
