The Yamaha RPZ50 Venture MP high beam and low beam headlight bulb size is 9003 for both applications. The replacement chart covers vehicle production years spanning 2013 to 2014.
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 for the Yamaha RPZ50 Venture MP across all listed positions and years, covering both high beam and low beam headlight functions for 2013-2014.
The 9003 is an ANSI-standardized bulb designation used in the United States and Canada, making it a regionally defined specification rather than a universal global standard.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate tungsten filaments within one glass envelope, one dedicated to high beam output and one to low beam output.
The high beam filament operates at 60 watts, while the low beam filament operates at 55 watts, both running on a 12-volt electrical system.
The P43t base type is a bayonet-style mount with a 43mm flange, which physically locks the bulb into the headlight housing and ensures correct filament alignment relative to the reflector.
Because the 9003 serves both the high beam and low beam positions on the RPZ50 Venture MP, the same bulb part number applies to both headlight circuits, though each filament within the bulb is activated independently by the vehicle's electrical system.
The 9003 designation is functionally equivalent to the H4 bulb used in international markets, sharing the same dual-filament design and P43t base, though the two designations originate from different standardization bodies and are not always interchangeable without verification.
