The Husqvarna 701 uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2016 to 2021 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 Husqvarna 701 (2016-2021) uses the 9003 bulb for both high beam and low beam headlight positions.
The 9003 is an ANSI-standard designation recognized in the United States and Canada, making it equivalent to the internationally designated H4 bulb, which shares the same dual-filament halogen construction and P43t base.
As a dual-filament bulb, the 9003 serves both beam functions from a single unit, which is why the high beam and low beam positions on the 701 share the same bulb specification rather than requiring separate bulbs.
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 P43t base is a bayonet-style mount with a 43mm collar, and correct base fitment is a critical factor when substituting or upgrading the bulb, as physically similar bulbs with different base types are not interchangeable.
