The Victory Gunner uses 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2015 to 2017 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 9003 bulb is the sole bulb type listed across all headlight positions in the Victory Gunner specifications, covering model years 2015-2017.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
Because the 9003 serves both the high beam and low beam positions in the Victory Gunner (2015-2017), a single bulb type handles the full headlight function rather than requiring separate bulbs for each beam.
The 9003 operates on a 12V electrical system, which is standard for motorcycle applications.
The 9003 uses a P43t base, a bayonet-style mount with a 43mm flange width, which physically determines socket compatibility and is not interchangeable with other base types.
The 9003 carries an ANSI designation applicable in the United States and Canada, indicating it conforms to a standardized specification for those markets.
The 9003 and H4 bulbs share the same dual-filament design and P43t base, making them functionally equivalent in many applications, though the designations reflect different regional standards: 9003 for North America and H4 for international markets.
