The Yamaha VX500 VMAX 500 headlight bulb uses a 9003 size for both high beam and low beam applications. The replacement chart covers vehicle production years spanning 1994 to 2001.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Yamaha VX500 VMAX 500 uses the 9003 bulb for both high beam and low beam headlight positions across all listed model years from 1994-2001.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it the North American equivalent of the internationally designated H4 bulb.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one housing.
The bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount with a 43mm collar, a fitment standard shared with the H4 designation used in international markets.
Because both the high beam and low beam positions call for the same 9003 bulb across all listed years, only one bulb type is required to service the entire headlight assembly on the VX500 VMAX 500.
The P43t base is not interchangeable with single-filament bases such as the P14.5s used in H1 or H3 bulbs, and substituting a single-filament bulb would not replicate the dual-function design of the 9003.
