The Yamaha XV1900 Roadliner uses an H7 bulb size for high beam headlight operation and a 9006 bulb size for low beam headlight operation. The replacement chart covers 2006 through 2014 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 Yamaha XV1900 Roadliner uses two distinct bulb types across its headlight system: the H7 for high beam and the 9006 for low beam, across the 2006-2014 model years (excluding 2011).
The H7 is governed by the ECE standard, which applies across Europe and much of the world, though it also carries approval in the United States and Japan.
H7 bulbs use a PX26d base, a two-pin connector with a locking ring that physically differs from the base found on the 9006.
The 9006 follows the ANSI standard, which is the regulatory framework used in the United States and Canada.
The 9006 uses a P22d base, a three-tab bayonet-style connector that is not interchangeable with the PX26d base of the H7.
Both the H7 and the 9006 are single-filament halogen bulbs rated at 12V and 55W, meaning each bulb serves only one lighting function rather than switching between two.
Because the H7 and 9006 use different base types, the high beam and low beam sockets on the Yamaha XV1900 Roadliner are not interchangeable with each other.
Although the H7 and 9006 share identical wattage and voltage ratings, substituting one for the other is not possible due to the physical incompatibility of their respective bases.
