The Yamaha XVS950 V Star 950 uses a P21/5W bulb size for front turn signals and a 12496 bulb size for rear turn signals. The replacement chart covers 2014 to 2015 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 XVS950 V Star 950 uses two distinct bulb types across its front and rear turn signal positions for the 2014-2015 model years.
The front turn signal position on the XVS950 V Star 950 calls for the P21/5W, an ECE-standard dual-filament bulb rated at 12V with a 21W main filament and a 5W secondary filament.
The P21/5W uses a BAY15d bayonet base, which is an offset twin-pin fitting. The offset pin placement prevents the bulb from being seated in the wrong orientation, which matters when both filaments serve different signaling functions.
Because the P21/5W carries two filaments, it is capable of serving both a turn signal and a secondary function such as a running or position light within a single housing.
The rear turn signal position on the XVS950 V Star 950 uses the 12496, a part number associated with Philips and Osram. It is a 12V halogen bulb designated for specialty applications.
The front and rear turn signal positions on this motorcycle are not interchangeable, as they require different bulb types with different bases and filament configurations.
The P21/5W is governed by ECE regulations, meaning its output and construction conform to standards used across Europe and other international markets.
Halogen technology in the 12496 produces light through a tungsten filament enclosed in a halogen gas environment, which extends filament life compared to standard incandescent bulbs by redepositing evaporated tungsten back onto the filament.
