The Yamaha YXE70 Wolverine uses HS1 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2016 to 2017 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 HS1 bulb is the sole bulb type specified for the Yamaha YXE70 Wolverine, covering both the high beam and low beam headlight positions across the 2016-2017 model years.
The HS1 is a dual-filament halogen bulb, meaning a single unit contains separate filaments for both high and low beam functions within one housing.
The HS1 operates on a 12-volt electrical system and carries a 35W/35W power rating, with each wattage figure corresponding to one of the two filaments.
The HS1 uses a PX43t base, which is a specific bayonet-style fitting. A bulb with a different base type is not a direct physical replacement, regardless of voltage or wattage compatibility.
The HS1 is governed by ECE standards, a regulatory framework recognized across Europe and numerous other markets worldwide, which defines its output and construction requirements.
Because the HS1 serves both beam positions on the Yamaha YXE70 Wolverine, both headlight functions are affected if the bulb fails, as both filaments reside in the same unit.
