The Yamaha YP400 Majesty uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years from 2005 to 2014 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 Yamaha YP400 Majesty uses the 9003 bulb size for both the high beam and low beam headlight positions across the 2005-2014 model years covered in these specifications.
The 9003 is an ANSI-standard bulb designation recognized in the United States and Canada, making it a widely available halogen type in the North American market.
As a dual-filament bulb, the 9003 serves both beam functions from a single unit, which is why the same bulb size is listed for both the high beam and low beam positions on the YP400 Majesty.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 bulb type is electrically equivalent to the H4 bulb, sharing the same dual-filament design and P43t base. However, the H4 designation follows European ECE standards, while the 9003 follows ANSI standards, and housing fitment compatibility between the two should be confirmed before substitution.
