The Yamaha YXM700 Viking VI headlight bulb uses an HS1 size for both high and low beam functions. The replacement chart covers 2015 to 2019 production 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 YXM700 Viking VI uses the HS1 bulb type for both high beam and low beam headlight positions across the 2015-2019 model years.
The HS1 is a dual-filament halogen bulb, meaning a single bulb contains separate filaments for both high and low beam functions within one housing.
The HS1 operates at 12 volts with a 35W/35W power rating, where each wattage figure corresponds to one of the two filaments.
The HS1 bulb uses a PX43t base, which is a specific bayonet-style fitting associated with motorcycle and powersport applications. This base type is not interchangeable with common automotive bulb bases such as H4 or H7.
The HS1 is governed by ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, distinguishing it from bulbs designed solely to DOT standards used in North America.
Because both the high beam and low beam positions share the same HS1 specification, a single bulb type serves the entire headlight assembly on this vehicle.
