The Yamaha XVS950 Bolt uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 2014 to 2020 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 9003 is the sole bulb type specified across all headlight positions on the Yamaha XVS950 Bolt, covering model years 2014-2020 for both high beam and low beam functions.
The 9003 is a dual-filament halogen bulb, meaning a single physical bulb contains two separate filaments: one rated at 60W for high beam output and one at 55W for low beam output.
The 9003 operates on a 12V electrical system and uses a P43t base, which is a bayonet-style mount with a 43mm collar width.
Because the Yamaha XVS950 Bolt uses the 9003 for both the designated high beam and low beam positions, the motorcycle likely relies on a single-headlight housing where the dual-filament bulb handles both functions rather than separate housings for each beam.
The 9003 is defined under ANSI standards and is the designation used in the United States and Canada. It is electrically and physically equivalent to the H4 bulb designation used in international markets, making cross-regional substitution possible under that equivalency.
The P43t base is not interchangeable with single-filament bases such as the P14.5s used on H1 or H3 bulbs, meaning only dual-filament bulbs sharing the P43t fitment are compatible with this socket.
