The Yamaha XV1000 Virago uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 1984 to 1985.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is an ANSI-standard dual-filament halogen bulb rated at 12 volts, with a high beam filament drawing 60 watts and a low beam filament drawing 55 watts. It uses a P43t base, which is a bayonet-style mount common in motorcycle and automotive headlight applications.
The Yamaha XV1000 Virago uses the 9003 bulb for both the high beam and low beam headlight positions across the 1984-1985 model years.
Because the 9003 is a dual-filament bulb, a single unit serves both beam functions within one housing, rather than requiring separate bulbs for each beam.
The P43t base designation indicates a 43mm base with a three-pin bayonet fitting, which physically locks the bulb into the housing at a fixed rotational position to maintain correct filament alignment.
The 9003 bulb is recognized under ANSI standards as used in the United States and Canada. It is electrically and physically equivalent to the international H4 designation, meaning bulbs sold under either designation share the same base, voltage, and wattage ratings.
The consistent use of the 9003 across both beam positions and both model years means a single bulb type covers all headlight fitment needs for the 1984-1985 XV1000 Virago.
